Paris Hilton may have more money than sense but she is still likely to rather unhappy about losing her prized motor during a game of poker.

The hotel heiress bet her Bentley on an ill-fated hand during a session at the family casino in Las Vegas.

"I'm obsessed with poker," the 25-year-old Hilton admitted. "It's my favourite game. I'm really lucky in Vegas, I always win."

Well, not that lucky it seems.

And it appears all bets are off on the chances of her winning her Bentley back as her folks, Rick and Kathy Hilton, have banned her from gambling at their casino.

However, with an estimated personal fortune of $30 million, the Simple Life Star and aspiring silver screen actress is unlikely to be having to grab lifts for too long.
