Rihanna's pop star boyfriend Chis Brown was caught flirting on the dance floor with a group of girls in Liverpool, according to eyewitnesses.

The With You star is said to have been lapping up the female attention he was receiving when an annoyed Rihanna burst in to break up the party.

An onlooker tells The Mirror, "Chris invited them for a glass of Cristal.

"Then, as he started getting into the music, they had a dance-off. That was when Rihanna walked in.

"She was suffering from a cold so she was in a bad mood anyway."

It seems that the Disturbia star couldn't handle her man having a few admirers.

The source adds, "The girls were asked to move away from Chris."
