Rihanna and Chris Brown tried to enjoy a night out at L.A. club Greystone Manor on Feb. 3, but their party was interrupted when Karrueche Tran showed up on the arm of a new guy. While the couple left shortly after the model’s arrival, we’ve learned that Rihanna, 24, paid her romantic rival no mind!

A source close to the Unapologetic singer told HollywoodLife.com exclusively that there isn’t anyone on Earth who can make Rihanna uncomfortable enough to leave a club, even though she did give Karrueche, 24, the cold shoulder.

“Rihanna has no reason to be uncomfortable no matter where she goes, believe that,” our insider says.

“She saw Chris’ piece in the club, but it wasn’t nothing crazy or nothing awkward at all. She didn’t go and speak or no s**t like that. She just paid that girl and the whole situation like taxes…That’s my b***h though, she would never trip on the next b***h.”

Though Rihanna and Chris, 23, both left their group of famous friends — including Ne-Yo, Wiz Khalifa, Soulja Boy, and Afrojack — rather quickly, once Karrueche arrived, our source says that their visit was always intended to be brief.

“Rihanna kicked it with the girls all day yesterday and later, after the game, she hit Chris up and they talked and planned on rolling out to Greystone,” the friend says. “But she stopped by the club for hot minute, had a drink with Chris then she hit it. It was just a quick meet up after she’d been in the house and working and watching the game with girls.”

This is not the first time that Karrueche Tran has bumped into her love rival Rihanna in an LA nightclub, but this time, it was Rihanna who left early — and she took Chris Brown with her!
