Pictured: Chris Brown and Rihanna cosy up at party... but leave in separate cars

Rihanna and Chris Brown have been pictured getting close at a party in Los Angeles on Saturday night. Neither of the pop stars have officially admitted they are back together but have been spotted in some very cosy situations recently and don't seem to care who knows about it. The pair were at the same event in Beverly Hills on and sources tell HollywoodLife they were also seen 'kissing and hugging'. However, both singers left the venue separately in different cars.

Brown grinned cheekily and looked pleased with himself as he manoeuvred out of his parking spot with a young male friend in the passenger seat. The Look At Me Know singer was wearing his trademark baseball cap and a grey jumper and of course his customary bling was on show too.

Brown split from his last girlfriend Karreuche Tran recently and rumours were rife that it was because of his friendship with former flame Rihanna. Model Tran and Brown dated for a more than a year but it is believed the relationship turned sour as soon as Rihanna was in the picture again. And the Diamonds star obviously wanted to remind Tran who was still number one in Brown's affections as recently as Friday. Rihanna tweeted what is believed to be a very obvious dig at Tran, calling her a 'chore'. Happy guy: The star seemed in high spirits as he drove off with a male companion Happy guy: The star seemed in high spirits as he drove off with a male companion She wrote on Friday night: 'If you start feeling like a 'chore' to someone, you probably are!' Brown is still on probation for assaulting Rihanna in 2009 but the Diamonds star can't seem to stay away from her bad boy ex-boyfriend. They have been spotted numerous times over the last few months at the same parties, clubs and events but neither have officially come out and said they are back together. At the start of October there were reports that the pair sneaked into a bathroom of a club in New York for 20 minutes and people at Griffin nightclub in the Meatpacking district, also claim they saw Brown and Rihanna kissing.

He has his arm draped over the back of Rihanna's chair and the picture is captioned, simply: 'Breezy. Rih Rih.' Rihanna's new album Apologetic is due for release on November 19 and as soon as that's out the way, it is widely believed the pair will go public with their rekindled romance. Despite Brown attacking Rihanna on the eve of the Grammy Awards in 2009 her family are still behind him. Her father Ronald Fenty reportedly called Brown 'a super guy' and said the family had always loved him.
