London - Rihanna "refused" to sit with Chris Brown during a night out on Wednesday (13.02.13).
The on/off couple have sparked speculation they have ended their romance again after the 'Stay' hitmaker refused to be seated near her 'Don't Wake Me Up' singer beau at Popular Demand's one-year anniversary party at the Playhouse night club in Los Angeles, and the pair ignored each other all night.
A source told the MailOnline: "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.
"He promptly ordered three more bottles of ace of spades which came out with in a procession of sparklers and scantily clad cocktail waitresses, causing a spectacle, which he clearly wanted Rihanna to see."
Rihanna, 24, and Chris, 23, are said to have arrived at the club separately and left separately at the end of the night, with the 'Turn Up the Music' singer leaving at 2.15am and the 'Diamonds' starlet leaving around 3am.
The frosty atmosphere between the singers comes days after they were seen cosying up at the Grammy Awards on Sunday (10.02.13) where they sat next to each other, laughing and flirting all evening.
Following months of speculation, Rihanna recently appeared to confirm the couple had reconciled following Chris' attack on her in 2009. - Bang Showbiz
