Pam and Tommy 3rd Times a Charm

July 19, 2005 -- PAMELA Anderson is hoping her third wedding with Tommy Lee will be the charm. Lee — who has already walked down the aisle twice with Anderson — popped the question again on Friday at the Palms Hotel & Casino in Las Vegas, our spy reports. "He got her a black diamond with two gray diamonds on the side. After she said yes, they flew on the Palm's private jet back to L.A. — but they crossed out the 'l' on the side of the jet so it said 'Pam's.' " The kooky couple then shacked up at the Mondrian for the weekend and told pals the wedding would happen "this week." A rep for Anderson said, "I don't think so," but then didn't call back after promising to check.
