As Chris Brown and Rihanna cuddled at the Grammy Awards Sunday, Brown’s ex-girlfriend Karrueche Tran flaunted her new boyfriend as they partied alongside several hip-hop heavy hitters.

Tran and her new beau, public relations mogul J. Ryan La Cour, were spotted at a Grammys after-party at Hyde nightclub, where they hung out with the likes of Diddy and Drake, according to the Daily Mail. The couple also attended a Vibe magazine event that weekend.

La Cour notably shared several photos of their activities on his Instagram page, while other images of the two at the Hennessey-sponsored Grammys event have also surfaced.

Several outlets suggest that Tran chose this night to step out in her new relationship to make Brown jealous.

In a recent interview with Rolling Stone, Rihanna revealed that she and Brown had in fact rekindled their relationship after they’d spent several months teasing to public as to their status.

Tran, a fashion designer who runs The-Kill, the women’s division of Brown’s clothing line Black Pyramid, told Rolling Out magazine that she will always be friends with the singer that she dated between 2010 and 2012, following the tumultuous first run of his relationship with Rihanna that ended in domestic violence.

“It is what it is at this point. We’re still gonna be friends.  Because at the end of the day he was my best friend.  And we have a business together.  There’s no way around it,” Tran told the magazine.

Rihanna and Brown attended a Grammy party at the Supper Club in Hollywood following the big show, where they reportedly partied until very late and then went back to Chris’ place, according to Hollywood Life.
