Demi Moore gave her new husband, Ashton Kutcher, a birthday party to remember on 4 February (06) by inviting the best speaker she knows to toast the PUNK'D star - her ex-husband.

Bruce Willis was on hand to wish Kutcher the very best as the actor/TV prankster turned 28 at the Regent Beverly Wilshire hotel's rooftop terrace in Los Angeles.

Guests at the reported $100,000 (GBP55,500) party included Chris Rock, David Spade and Naomi Campbell.

One party guest tells American publication In Touch, "There were poker and blackjack tables, and Bruce was even giving Ashton some poker tips."

All guests were reportedly given a chip worth $500 (GBP278), as they walked in to the bash, and a chance to win a high-definition TV if their luck held out.
