Kendall Jenner pretty much stole the show at the amfAR 22nd Cinema Against AIDS Gala event in Cannes on Thursday night, and it wasn't just because of her gorgeous purple Calvin Klein dress!

The 19-year-old stunner, who was joined by fellow model pals like Hailey Baldwin and Gigi Hadid, spent quite a bit of time chatting with singer Rita Ora, who famously dated Kendall's older brother Rob (and pissed off most of the Kardashian family after the two broke up). In case you forgot, Rob claimed Rita cheated on him with "20 dudes" and slammed her on Twitter, and the feud escalated from there. Rob later tweeted, "I posted what I posted to keep myself from taking her back. Every time she messed up, I took her back for over a year now. I just had to do that to make her hate me."

Well, he certainly didn't make her hate Kendall! Good to see that there's no bad blood between the ladies...
