Blac Chyna reportedly has a twisted crush on Kanye West. Rumor has it, Rob Kardashian's baby mama is trying to steal his sister and her former pal Kim Kardashian's husband following her breakup with her fiance.

"[Blac]'s always found him [Kanye] highly attractive and has told a number of gal pals that she'd sleep with him in a heartbeat," a source close to the "Rob & Chyna" star tells OK!, "For months she's been cooking up ways to spend more time with him, hoping to make a move when Kim's not around."

The source continues, "Poor Rob had no idea, he's been played like a total fool by Chyna, who's been laughing at him behind his back the whole time they were together and openly going after other men. But hitting on Kanye was a low blow even by her standards."

Rob and Blac may not be back together in the future as they have been conspicuously silent on social media following their split. "This breakup feels more real because both of them are very calm," a source previously told Us Weekly. "In a romantic relationship, Rob doesn't trust Chyna at all. They both had major trust issues, and they grew apart."

The source added, "[However], the fighting is over for now. Rob's family isn't happy or sad about it; they just want Rob to be happy and that relationship wasn't making either of them happy anymore. Rob and Chyna know and understand that they aren't meant to be together."
