Not even a dead body in your ex wife's pool can throw off an already planned man date!

The morning after a dead body was found floating in Demi Moore's pool, Bruce Willis had lunch with Underworld director Len Wiseman at Tavern in Brentwood, Calif.

Early Sunday, a 21-year-old man was found dead in the pool at Demi Moore’s West Hollywood home. The victim was discovered at the bottom of the pool just a few hours after a party was reportedly thrown at the residence. No other details are known at this time, but police are currently investigating the tragic accident.

You'd think the father of Tallulah Willis, whose recent pool parties have come under the microscope following the death, would be at his daughter's side so soon after such a shocking event. But apparently not. A man's gotta eat with his boyz!

Outfitted in a black Polo shirt, jeans and a baseball cap, the father of five had an animated conversation with Kate Beckinsale's hunky hubby.
