Rihanna crashes Karrueche Tran's club party

'Diamonds' singer and entourage shows up at club party to celebrate model Tran's 'Rolling Out' magazine cover, may be making peace with former romantic rival

Is Rihanna making peace with a fellow rude girl?

The Barbadian beauty, 24, was spotted exiting Playhouse nightclub with a bevy of friends on Thursday night.

It was the same time at the same club that Karrueche Tran, the model ex-girlfriend of Rihanna's on-again off-again flame Chris Brown, was throwing a party to celebrate her cover of 'Rolling Out' magazine.

Rihanna's appearance was likely no accident. Brown was also in attendance, but stayed in the background in order to give Tran the spotlight.

Despite their complicated past, the 'Diamonds' singer has been cozying up to Brown in recent months.

The pair recently confirmed that the two are working on another single together, a follow-up to the pointedly named "Nobodies Business" on Rihanna's new album "Unapologetic."

Not everyone is happy about the return of the warm and fuzzies to Rihanna and Brown's relationship.

'Girls' creator Lena Dunham expressed disappointment at Rihanna for returning to an "abusive" ex.

"She gets back together with [HIM]and posts a million pictures of them smoking marijuana together on a bed…it cracks my heart in half," Dunham said.
