• Travis Scott recently released a new song called "Watch," featuring Lil Uzi Vert and Kanye West.
• Fans are convinced that they can hear Kylie Jenner's voice in the song's outro, speaking lyrics that seem to reference the couple's daughter Stormi.
• Jenner is credited with "additional vocals" on Genius, a website that allows edits from both fans and artists.
• The lyrics were originally listed as "We got bust down Rollies, bust down Rollies / And I told him I wanted to have a bust down baby."
• The second line has now been adjusted to, "And I told him I needed him to bust me down in the AP," based on a fan's correction.

Kylie Jenner and Travis Scott have been together for little over a year, but they have already clocked a number of relationship milestones — including welcoming their first child, daughter Stormi, in February.

Now it seems that the rapper and reality star are collaborating professionally. Scott recently released a new song called "Watch," which features contributions from rapper Lil Uzi Vert, Scott's pseudo brother-in-law Kanye West, and possibly Jenner herself.

In the last 30 seconds of Scott's song, a feminine voice can be heard speaking (or some say, rapping) a couple of lines. Many fans are convinced that the voice belongs to Jenner — and that she references the couple's daughter in the lyrics.

Because the actual words are muffled and difficult to hear clearly, fans have been speculating that Jenner was saying, "We got bust down Rollies, bust down Rollies / And I told him I wanted to have a bust down baby.""Bust down" is a colloquial term for "expensive," particularly when it comes to jewelry or watches, like a Rolex.

"This may be a reference to Kylie and Travis' baby, Stormi Webster," reads an annotation on the popular music website Genius. "It is no surprise that Kylie would compare the preciousness of her child to the preciousness of diamonds and jewelry."

Indeed, Genius credits Jenner with "additional vocals." But while the site allows artists to confirm lyrics and add commentary, it does not appear that Scott has made any verifications or comments on the page.

Additionally, the outro lyrics have already been edited once, according to an annotation from a Genius contributor. Jenner's best friend, Jordyn Woods, had apparently commented on an Instagram post using the correct lyrics: "And I told him I needed him to bust me down in the AP."

Whether or not Jenner's voice is actually featured, she definitely approves of the song. It can be heard in the background of a recent Snapchat video she posted.

The track was originally teased during one of West's recent flurry of tweets. 

West uses his verse in "Watch" to name-drop his wife, Kim Kardashian West, as well as to touch upon his recently revealed opioid addiction. He raps, "Wanna know how I feel? Step into my minefield / Wanna know how pain feels? I got off my main pills / Bet my wifey stay close, she know I'm on my Bezos / Opioid addiction, pharmacy's the real trap."
