London, Jan 24 : Rihanna has fuelled rumours of a reunion with her violent ex-lover, Chris Brown after they were seen partying in the same club.

The sexy singer and her former boyfriend enjoyed a night out at Hollywood's Greystone Manor, on Sunday night, the Daily Star reported.

Although the two left separately, friends fear that the `Umbrella' star wants to give their fiery relationship another go.

Brown, 22, and Rihanna, 23, had split in 2009 after he beat her up.

A leaked photograph from Los Angeles police showed the singer with horrific bruises and cuts on her face.

He was given five years' probation and six months' community service.

A restraining order banned him from being within 50 yards of the R&B star.

But she has since gone to court to relax the order's conditions. (ANI)
