Chrissy Teigen and John Legend are celebrating 5 years of marriage — here's a complete timeline of their relationship

Chrissy Teigen and John Legend boast one of Hollywood's most beloved marriages. Fans are so often delighted by their playful social media personalities and supportive moments that it's easy to forget how long they've been together.

On Friday, September 14, Teigen celebrated the couple's fifth wedding anniversary on Instagram and called Legend "the man of my dreams."

"We have two babies and some pups and a life I am grateful to have," Teigen wrote in the caption. "My everything, I love you and am so proud of the story we've created."

Here's a look back at their love story.

September 14, 2006: They met on the set of Legend's music video for "Stereo."

Twenty-year-old Teigen and 28-year-old Legend first met on the set of Legend's music video for "Stereo," in which Teigen starred as Legend's love interest.

"I walked into John's dressing room to meet him, and he was ironing in his underwear," Teigen told Cosmopolitan in 2014. "I said, 'You do your own ironing!?' He said, 'Of course I do.' I gave him a hug."

Teigen also revealed to Cosmo that they went back to Legend's hotel room after the shoot, ate In-N-Out burgers, and "hooked up."

"We did the music video, we were together for like 12 hours," Teigen told Wendy Williams in 2014. "We spent the entire day together, me in my underwear and him in a full suit, and I went to go say goodbye to him, to his hotel and we didn't ever say goodbye that night."

Over the next year, they remained in touch but didn't define their relationship.

Shortly after the two met, Legend went on tour to promote his most recent album, "Once Again." Teigen told Cosmo in 2014 that for the next year, they texted and spoke on the phone while she tried to control her jealousy.

"I let him be himself for a while," she said. "The worst thing you can do is try to lock someone like that down early on, then have them think, 'There's so much more out there.' I played it cool for a long time. Never once did I ask, 'What are we?'"

"Marriage was never my goal, because I've never been very traditional. I was just happy to be with him."

For Legend's part, he said that he fell in love with her during that time.

"We were texting a lot, and I started to see her sense of humor," he told ET in 2016. "We would talk on the phone, and I started to fall in love with how engaging and witty and funny she is."

"Once we started spending more time together between tour stops and all this other stuff, we realized we had such a connection," he continued. "I wasn't nervous about it. When you feel a real connection to somebody, for me it wasn't nerves, it was more like excitement. 'Oh, this could be great.'"

Around this time, they broke up — for half an hour.

"Early on in the relationship, I was on tour with him and he'd gotten sick," Teigen revealed to Cosmo in 2016. "He was feeling really bummed and stressed out. He was like, 'I can't be in a relationship right now.'"

"That lasted for one day. Literally, a day," she continued. "I knew it came from a place other than us not working."

Legend told The Guardian in 2017 that he was "really stressed and busy," but after his feeble attempt to end it with Teigen, they were back together less than half an hour later.

"I was just like: 'I'd just be happier single right now,'" he recalled. "And she was like: 'No.'"
