Sisters typically share clothes, jewelry, and ex-boyfriends?! Kourtney Kardashian and French Montana were reportedly “all over each other” at P.Diddy’s 49th birthday bash on Sunday, Nov. 4, an eyewitness told Radar.

“Kourtney and French were on each other. She was twerking on him, he had his hand on her waist and a— and was whispering in her ear all night,” a source who attended the party revealed. It didn’t seem like Kourtney was worried about stealing her sister’s ex-boyfriend, though. The source continued, “She was eating it up. She was smiling in his face and was hand feeding him hors d’oeuvres.” Hmm, we hope Khloé was OK with this!

The pair appeared “too close for comfort” and were “looking like they wanted to do some X-rated things,” the source confessed. Kourtney appeared to be enjoying the attention, especially since she’s enjoying the single life since her split from Younes Bendjima.

The KUWTK star and the 25-year-old model went their separate ways this past summer, after nearly two years together. Since then, Kourtney has been seen with Grown-ish actor, Luka Sabbat, and now French Montana — clearly she is enjoying playing the field!

French doesn’t have any ill will towards his ex, Khloé, though. Even though the pair briefly dated in 2014, they have remained good friends. “She’s good, she’s good. I spoke to her last week. We’re great friends. I think we’re going to be friends forever,” French told E! News in 2016. The rapper has remained in the same social circle as the Kardashians too — he still hangs out with Scott Disick and Kanye West from time to time.

Khloé has been dealing with her own drama lately. Her baby daddy, Tristan Thompson, cheated on her and she has had to rebuild her relationship with him. A source told People, “Khloé wants so badly for True to have a happy family. She wants to do what’s best for her daughter, and to her, that means being with Tristan.”

Well, we just hope Khloé gives Kourtney her blessing!
