Khloé Kardashian and ex-boyfriend French Montana are reportedly nothing but good friends.

"Haven't you ever had a friend that was nothing but pure fun? That's what French is to Khloé," an insider told HollywoodLife.com. "He's a blast to be with -- the party never stops. There's absolutely nothing serious going on between Khloé and French. They're not even having sex. It's completely platonic, and French understands that."

The publication recently reported that the "Don't Panic" rapper is trying to win back the "Keeping Up with the Kardashians" star.

"He really wants to be exclusive with Khloé and is pulling out all the stops by sending her flowers, taking her on romantic nights out and buying her expensive gifts," another source said. "French is going all out to get Khloé."

However, it looks like Kardashian knows exactly where she wants French Montana.

"Khloé always puts French in his place. They were recently having fun and dancing -- it was an innocent dance until French tried to get slick and put his hand on her butt. She gave him a death stare, shook her head and said, 'Uh uh, you know that isn't for you,'" the source said.

"French was like 'If it isn't mine then whose is it?' Khloé turned around, put her butt in his crotch area and grinded on him tough. Then, she bent all the way over, twerked on him real good, touched her ankles and threw up the peace sign behind her back so French could clearly see L.O. tattooed on her hand."

According to the source, the rapper "got the message" right away and said he "was wrong."

"They kept it cool, though, and danced some more, but French knows that he's getting nowhere," the source added. "He has decided to fall back."
