Rihanna "refused" to sit with Chris Brown during a night out this week.
The on/off couple have sparked speculation they have ended their romance again after Rihanna refused to be seated near Brown 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 Brown, 23, are said to have arrived at the club separately and left separately at the end of the night, with Brown leaving at 2.15am and Rihanna leaving around 3am.
The frosty atmosphere between the singers comes days after they were seen cosying up at the Grammy Awards on Sunday 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 Brown's attack on her in 2009.
