Demi Moore Throws A-List Birthday Bash for Husband Ashton Kutcher

With a star-studded bash – featuring Madonna, Kate Hudson and his wife's ex husband Bruce Willis!

His wife Demi Moore threw Kutcher a birthday dinner at Gemma restaurant in NYC's Bowery Hotel last night.

Among the guests: Willis and his model-girlfriend Emma Heming; Salma Hayek and her fiance François-Henri Pinault; famed producer Guy Oseary and Madonna, who brought him a gift and sang him "Happy Birthday!"

(Rabbi Yehuda Berg and other Kabbalahists also attended, squashing online rumors that the Kutcher and Moore have cut ties with the religion.)

The crew then headed to NYC hot spot Socialista, where Lucy Liu, Liv Tyler, Hudson, fashion designer Roberto Cavalli and Eric Dane and wife Rebecca Gayheart were spotted.

A few hours later, a half-eaten cake was brought out of the club and put in the back of a truck.

Kutcher and Moore were the last to leave.

The night before, Kutcher and Moore attended Madonna's $2,500-a-plate, Gucci-sponsored UNICEF benefit at the United Nations.
