Victoria Beckham is upset over reports that David Beckham enjoyed a flirt-fest with a mystery brunette, NW reports.

With plenty of time on his hands and no wife around to restrain him, sources say David has been partying up a storm, bar hopping and lapping up attention from the ladies.

On one especially drunken night out at Chicago nightclub Krem, the footballer stunned his fellow club-goers by openly sharing romantic moments with a stunning woman. "He was sitting alone in a corner of the VIP room with a hot brunette," says an onlooker.

"They were whispering and getting very cosy," says one onlooker
