Willis dating Playboy beauty?

Bruce Willis has a new girlfriend - former Playboy Playmate Karen McDougal.

The couple were photographed canoodling on a yacht in the Mediterranean Sea during a Sardinian holiday earlier this month, and friends believe Demi Moore's former husband has fallen for the 36-year-old model.

A source tells American magazine Star: "They were cuddling the whole time and couldn't keep their hands off each other".
