MISCHA BARTON's ex-boyfriend BRANDON DAVIS was left red-faced by his claim he won $300,000 (GBP166,600) in Las Vegas, Nevada, after the casino announced he had only won $1,500 (GBP830).

The oil heir, who dated THE OC beauty for 18 months until their June 2005 split, boasted to Las Vegas Review Journal columnist NORM CLARKE that he had won the hefty prize while playing blackjack at the Mirage Hotel And Casino.

However, in a statement to gossip site PageSix.com, a representative for the Mirage says, "Mr Davis played for approximately three hours and only won a total of $1,500."
