Justin TimberlakeJustin Timberlake has reportedly dumped girlfriend Cameron Diaz as he prepares to release a new album and go on a world tour.

A source has told US gossip columist Janet Charlton that Justin dumped Cameron last week after a fight over his antics at a party in Las Vegas - but that was just really the straw that broke the camel’s back.

The source revealed: “Cameron is ready to settle down and wants a commitment, even though she might not admit it. Justin is only 25 and he’s been with Cameron for three years. He hasn’t had a chance to sow his wild oats yet.”

“Justin is poised to leave on a world tour and he wants to be free.”

Justin’s spokesperson has dismissed the rumours as nonsense but there has yet to be a confirmation or denial from Cameron’s camp. The actress is said to be “devastated” over the split.
