Who said you can't be friendly with your siblings' exes?
Kendall Jenner proved this Thursday night, when she happily posed next to Rita Ora at AmfAR's 22nd Cinema Against AIDS Gala in France. The 24-year-old "Black Widow" singer dated her brother Rob Kardashian in 2012.
Rob and Rita had their fair share of drama after their breakup, with Rob taking to Twitter in December 2012 to air out some pretty nasty allegations about an ex -- which plenty of fans assumed was about the British pop star.
"She cheated on me with nearly 20 dudes while we were together, I wonder how many she will sleep with now that we are apart?" he tweeted, then later deleted. "I just don't get how a woman can do that to her body. And your career hasn't even launched yet... This is a lesson to all the young women out there to not have unprotected sex with multiple men, especially while in a relationship."
Rita finally reacted to the tweets last April during her appearance on Power 105.1's radio program The Breakfast Club.
"I think people react to things differently and like to express their feelings in certain ways," she mused. " ... But it was a phase and a moment in my life and now, you know, onward and upwards. Don't get me wrong, he's a great dude."
Rita, however, was far from the only star Kendall got friendly with at Thursday night's star-studded amfAR gala. She also busted out some moves with fellow supermodels Doutzen Kroes, Joan Smalls, Lara Stone (who most will recognize from her Calvin Klein ads with Justin Bieber), Jourdan Dunn, and Karlie Kloss.
