His three daughters and former wife Demi Moore, her husband Ashton Kutcher, and friends Kevin Costner, Ben Affleck, Billy Bob Thornton, Don Johnson and Sylvester Stallone were among the crowd watching the ceremony, TMZ.com reported.
"I used to come down here and look at these stars and I could never quite figure out what you're supposed to do to get one," Willis said. "And time has passed and now here I am doing this, and I'm still excited about it. I'm still excited to be an actor."
Willis rose to fame in TV's "Moonlighting" and won the Emmy for outstanding lead actor in 1987. Since then, he has achieved fame as a big screen action star, counting among his credits "Die Hard," "Pulp Fiction," "The Sixth Sense," "Sin City" and "Armageddon."
"Over the Hedge," in which Willis voiced RJ the raccoon, comes out on DVD Tuesday and his fourth "Die Hard" film, "Live Free or Die Hard," is scheduled for release next summer.
