Double Brit Award winners Kings Of Leon apparently started thumping each other at this week's award afterparty.

The incident is alleged to have taken place backstage after bassist Jared Followill's missus caught him talking to a sexy member of pop-by-numbers star Alesha Dixon's entourage, and threw water over her.

However, according to the always reliable Sun newspaper, the bust-up had more to do with guitarist Matthew Followill. Apparently the six-stringer was becoming jealous at the lack of attention he was being paid by various females in comparison to his band mates, so he started a scrap with vocalist Caleb Followill.

The Sun quotes a source as saying: "Matthew's always the last one to be asked for an autograph. He hasn't been feeling part of things, especially at big events like the BRITs. Caleb was annoying him up all night, unintentionally, and all of a sudden something snapped and they just went for each other. It was like a proper old fashioned bar-room brawl."
