"happy birthday sexy @bellahadid" the 23-year-old reality star wrote on her Instagram Story.
The footage was originally shown in Travis Scott's documentary Look Mom: I Can Fly, which premiered in August on Netflix.
While it's a little awkward that Kendall is now posting anything from her sister's ex-boyfriend, it's a nice way to wish Bella a happy birthday.
The kiss was most likely done in good fun between two friends, however, in Kendall's cover interview for Vogue in April 2018, she addressed the copious amounts of rumours online assuming she was gay.
The rumours stemmed from how low-key she is with her relationships in comparison to the rest of her family.
“I like my private life,” she said in the interview. “I think it’s because I’m not like all my other sisters, who are like, ‘Here’s me and my boyfriend!’ So it was a thing for a minute because no one ever saw me with a guy. I would always go that extra mile to be low-key with guys, sneaking around all the time. You don’t want to, like, look crazy.”
“I don’t think I have a bisexual or gay bone in my body, but I don’t know! Who knows?!” she continued. “I’m all down for experience — not against it whatsoever — but I’ve never been there before.”
