Kevin FederlineKevin Federline is said to have been paid between $100,000 and $300,000 to appear at his own birthday party - but he hinted that he lost all that money in the casino before the event itself.

Kevin celebrated turning 30 at Pure Nightclub in Las Vegas on Friday with around 20 friends, including his attorney Mark Vincent Kaplan and the mother of his older children Shar Jackson - but, unsurprisingly, not his ex-wife Britney Spears.

At one point the wannabe rapper took to the mic to encourage everyone to have “a good time” and explained his croaky voice saying: “I lost my voice at the craps tables and I lost all my money [too].”

He was then spotted dancing on his table’s sofa and holding aloft one of his presents - a Californian license plate, reading “FDRLINE”.

However, before the group relocated to the late-night Noir Bar inside the Luxor hotel, Kevin was spotted having a less conspicuous moment with ex-girlfriend Shar.

A source told the New York Daily News that the former lovers were spotted snuggled down together on a sofa together: “They looked like a couple again.”

Kevin and Shar have two children, daughter Kori and son Kaleb, together but Kevin left Shar for Britney when the former actress was pregnant with Kaleb.
