Rihanna And Chris Brown "Ignore Each Other" On Night Out In Los Angeles

The 'Stay' singer has fuelled reports her relationship with the R&B star has cooled off this week.

Rihanna and Chris Brown reportedly ignored each other completely during a night out this week, sparking rumours that their relationship may be on the rocks.

The 'Diamonds' star arrived at the same club as 'Turn Up The Music' singer Chris in Los Angeles on Wednesday (13th February), but allegedly refused to acknowledge him and the pair are said to have not spoken at all during the evening.

According to reports, Rihanna demanded to be sat away from Chris when she arrived at the Playhouse nightclub, a far cry from the pair's behaviour at the Grammy Awards 2013 last weekend (10th February) where they were pictured sharing several cuddles.

"Rihanna refused to sit with or even near Chris, and when Chris noticed she was there he made a huge show of rubbing his presence in her face," a source told the MailOnline this week. "He promptly ordered three more bottles of ace of spades which came out with a procession of sparklers and scantily clad cocktail waitresses, causing a spectacle, which he clearly wanted Rihanna to see."

For Valentine's Day yesterday (14th February) Rihanna was noticeably without Chris when she attended Ne-Yo's Los Angeles concert on her own, dressed in a Grecian style orange gown and heading out to Club Boc to party with friends afterwards.

Rihanna only recently confirmed she and Chris Brown had reconciled after their break-up in 2009, saying she doesn't care if people believe it is a mistake because it's her "mistake to make".
