• Ariana Grande and Pete Davidson are reportedly engaged, just 24 days after initial reports claimed the two were "casually dating."
• News of their relationship broke in late May, shortly after they each broke up with longtime partners.
• Here's a complete timeline of the 24-year-olds' whirlwind romance.

Ariana Grande and Pete Davidson may be redefining the idea of a "rebound relationship" for the rest of eternity. Mere weeks after splitting up with longtime partners, the two 24-year-olds are reportedly engaged to each other.

If their fast-forwarded romance has given you whiplash, here's the break down of everything that has happened so far.

March 2016: Grande hosts "Saturday Night Live" and apparently meets Davidson, a cast member, for the first time.

At the time, both Davidson and Grande were in relationships with other people.

May 9, 2018: News broke that Grande and rapper Mac Miller had ended their two-year relationship.

TMZ reported that Grande and Miller — who began dating officially in September 2016, three years after collaborating on their romantic hit single "The Way"— had grown apart but remained close friends.

A day later, Grande confirmed their split with an emotional Instagram story.

"I respect and adore him endlessly and am grateful to have him in my life in any form, at all times regardless of how our relationship changes or what the universe holds for each of us! Unconditional love is not selfish. It is wanting the best for that person even if at the moment, it's not you," Grande wrote. "I can't wait to know and support you forever and I'm so proud of you!"

People later reported that the couple had officially split after Coachella in April — but that they had been struggling with their relationship "over last year."

"Ariana was holding Mac together for a long time and it wasn't a good relationship for her," a separate source told Us Weekly.

The two have since unfollowed each other on Instagram.

May 12, 2018: Grande and Davidson were spotted hanging out at a "Saturday Night Live" after-party.

Us Weekly later reported that she spent the night hanging out with Davidson and his mom, who had been featured on the show that week for the Mother's Day cold open.

That night, Grande was photographed with a cloud-shaped phone case that appeared to match Davidson's.

May 16, 2018: Davidson confirmed that he had split with his girlfriend of two years, Cazzie David.

Davidson revealed that the two were "not together anymore" during an interview on Complex's "Open Late with Peter Rosenberg," though he did not reveal why the relationship had ended.

"Very talented girl, she'll be great and she'll be fine," he said. "Yeah, I think she'll be OK."

Rosenberg then told him, "you're going to be OK," and Davidson responded, "yeah, probably."

May 17, 2018: Davidson posted a photo that clearly showcases a new cloud-shaped tattoo. 

Given that Grande had used the cloud emoji as an Instagram caption just days before, fans were on high alert. They quickly noticed that she appeared to have gotten a matching tattoo on her finger.

May 18, 2018: It was officially reported that Grande and Davidson were dating.

Bossip broke the news, which was later confirmed by sources at other outlets.

"Ariana and Pete are dating and it's casual," a source told Us Weekly on May 21. "It just started."

May 20, 2018: Davidson and Grande were spotted acting like a couple.

According to People, Davidson was backstage while Grande performed at the Billboard Music Awards on May 20.

"After Ariana's performance, they were backstage and he had his arm around her," an anonymous onlooker told People. "They seemed very lovey-dovey. He was hanging out with her and her friends with his arm around her. She seemed quite smitten."

A fan video also caught Davidson hanging out in the same area as Grande and her team, including her brother Frankie. (You can see Davidson for a split second at the very beginning as he walks out of the frame.)

May 23, 2018: Grande called her former relationship with Miller "toxic."

Elijah Flint, a Twitter user with 137 followers, decided to weigh in on Grande and Davidson's budding relationship — which, for some reason, seemed to include laying the blame on Grande for her ex getting arrested on charges of a DUI and hit and run.

"Mac Miller totaling [sic] his G wagon and getting a DUI after Ariana Grande dumped him for another dude after he poured his heart out on a ten song album to her called 'The Divine Feminine' is just the most heartbreaking thing happening in Hollywood," he wrote.

Grande slammed the tweet and its sexist implications, all while revealing that she and Miller had a "toxic relationship" but that she will "continue to pray" for her ex.

"I am not a babysitter or a mother and no woman should feel that they need to be," Grande wrote. "I have cared for him and tried to support him and his sobriety and prayed for his balance for years (and always will of course) but shaming/blaming women for a man's inability to keep his s--- together is a very major problem. Let's please stop doing that."

May 24, 2018: Davidson hit back at people saying he shouldn't date Grande because of his mental illness.

Davidson — who is open about his experiences with rehab, depression, and Borderline Personality Disorder (BPD) — addressed criticism of his new relationship without actually confirming the relationship.

"Normally I wouldn't comment on something like this cause like f--- you," he wrote. "But I've been hearing a lot of 'people with BPD can't be in relationships' talk. I just wanna let you know that's not true. Just because someone has a mental illness does not mean they can't be happy and in a relationship. It also doesn't mean that person makes a relationship toxic. Everybody is different and there are a lot of treatments for mental illnesses and I have done/am doing all of them."

Interestingly, around this time, Davidson and Grande began to like and comment on each other's Instagram posts with a startlingly high frequency. (If they had been interacting on social media before, it was so sparse that nobody had noticed — not even dedicated Arianators.)

May 29, 2018: Grande publicly supported Davidson during a stand-up comedy set.

Grande shared a photo of her new beau onstage in her Instagram story, captioning the photo with a set of blushing and heart-eyed emojis.

May 30, 2018: The couple made its official Instagram debut.

Davidson posted a photo of the two Hogwarts enthusiasts in their respective robes. He cheekily captioned the photo, "the chamber of secrets has been opened." Grande commented with a fairly predictable yet shockingly blunt "Harry Potter" pun: "u tryna slytherin."

May 31, 2018: Not to be outdone, Grande followed with her own post.

While it's presumably possible that casual friends could pose in matching Hogwarts robes amidst dating rumors, Grande's follow-up post left little to the imagination. The romantic snapshot eliminated any doubt about her thriving relationship with Davidson. 

"i thought u into my life 💭 woah ! look at my mind," she wrote in the caption, which many fans have taken to be lyrics for a yet-to-be-released song.

June 2, 2018: Davidson revealed a permanent homage to his new girlfriend — twice.

Davidson's tattoo artist posted photos of two small pieces that the comedian got to honor Grande. One is of the bunny ears from Grande's "Dangerous Woman" album cover and the other are the initials "A.G."

According to BuzzFeed, Reese originally captioned the bunny ears photo, "We had a good night somewhere in the hills of Los Angeles. Pete loves him some Ariana." But the caption has since been changed to a simpler "We had a good night."

June 3, 2018: Grande may or may not have debuted an engagement ring.

Not many people noticed — probably because Davidson's overflow of affection on his Instagram story acted as a suitable distraction — but Grande performed at Wango Tango with a massive sparkler on her left ring finger.

According to TMZ, the ring was custom-made by New York City jeweler Greg Yuna — and cost Davidson nearly $93,000. It reportedly took two weeks to make.

June 6, 2018: Grande joked about having kids with her boyfriend.

When Davidson posted a photo with a friend, adding the tongue-in-cheek caption, "I'm having his kids," Grande couldn't help but chime in.

"I look so good here," she commented.

June 7, 2018: Grande posted a video of Davidson defending his love of "Harry Potter."

We now have a pretty good idea of what these two discuss on a daily basis.

June 8, 2018: Grande and Davidson attended the "Kids See Ghosts" listening party and gave us another glimpse of the ring.

While giving an interview about her upcoming album, Grande seemed to be intentionally pulling her sleeves over her hands. (It didn't work.)

Davidson captioned a photo from the night with appropriate lyrics from the album: "feel the love."

June 9, 2018: Grande acknowledged that her Instagram is slowly transforming into a fan account for her boyfriend.

"i am but a pete davidson update acc stay tuned for more (pete follows / comments sumtimes)," she captioned a photo of the two of them.

Indeed, Grande's comment section has easily become the go-to spot for updates on Davidson's social media activity.

June 11, 2018: Multiple outlets reported that Davidson and Grande had gotten engaged.

The couple reportedly told people they were engaged on Saturday when they attended Robert Pattinson's birthday party in Hollywood, California.

Although the couple has yet to officially confirm this new development, Grande has been spotted making extremely interesting statements on Twitter.

The "No Tears Left to Cry" singer has responded to multiple fans reacting to the news of her engagement. In one particularly revealing tweet, Grande wrote that Davidson "has been briefed" on the implications of their future marriage (specifically that he would be "marrying us as well," as written by an excited fan).

Grande also responded with the word "crying" to a tweet that referred to her as "Mrs. Davidson."

June 11-12, 2018: The two have continued their tour of affection in Disneyland.

Many speculated that Grande and Davidson were at Disneyland to celebrate their reported engagement.

Grande posted multiple videos of Davidson as they rode Big Thunder Mountain Railroad together.

For the third video in a series of Davidson yelling ridiculously, she wrote, "when i get on top"— and quickly deleted it.

It is perhaps worth noting, as did Rolling Stones reporter Brittany Spanos, that Grande is in the midst of promotion for her newest album "sweetener" dropping in August. She also revealed on June 12 that she will be releasing a new perfume — and interestingly enough, the bottle is shaped like a cloud.

Whatever your thoughts on all this, rest assured: if you feel extremely shook, you are not alone.
