Pamela AndersonPamela AndersonPamela Anderson knows how to keep her man interested, right?

Erm, maybe.

Bruce Willis has hosted a celebration to mark the grand opening of the latest Planet Hollywood restaurant in Las Vegas.

The party, reported to have cost bosses more than £2m, attracted stars including Tom Jones, Sylvester Stallone, Nelly and Charlie Sheen.

The Planet Hollywood chain is rebranding after financial problems; new menus have been launched - including Demi Moore's recipe for "Chicken Crunch" - and expansion abroad is on the cards.

However, Pamela Anderson's new husband, Rick Salomon (of Paris Hilton sex-tape fame) seemed less than enthusiastic about the bash.

He barely cracked a smile as Pam schmoozed with the stars.
