*Is that a look of annoyance on Kim Kardashian’s face?

According to Radar Online, the reality star, 34, “threw a diva fit” when Chris Brown‘s on-again model girlfriend asked to take a photo with her at a recent event.

Karrueche Tran, 26, requested that they take a group picture together with their men at singer Teyana Taylor’s listening party in Hollywood this week.

“Kim said absolutely not and turned her down,” an insider tells Radar.

However, when Brown, 25, asked Kardashian’s husband Kanye West, 37, for permission to take the photo, the rapper happily obliged— leaving his wife with no choice but to participate.

“Kim cooperated, but made it very clear she was not happy about it,” the insider adds. “She acted like a complete b*tch. At one point, she even walked away while Karrueche was talking to her.”

The source claims there’s no bad blood between the two women; Kardashian simply thinks Tran is “lowbrow.”

“It was clear she believes she’s better than other people,” the insider explains of Kim K.
