Actor Bruce Willis offended a woman at a swanky New York party last week, by proposing her to have sex with him.

Apparently, Bruce was jocking around with some friend about the pick-up lines and asked a woman "What are your plans for sex tonight?" The woman got really angry and stormed out in a fury.

However, the star's lawyer, Marty Singer, defended his client, saying it was an innocent joke and he did not really want to bed her. "Bruce was joking around with some friends and talking about pick-up lines. One remembered an old pick-up line Willis used to use.

The friend said the line and Bruce may have repeated it - "but he was not trying to pick up the woman," Singer declared.

Bruce Willis split from his latest girlfriend, former opera singer Nadia Bjorlin, in April.

Willis was married to actress Demi Moore from 1987 to 2000 and have three children Rumer Glenn Willis (born 1988), Scout LaRue Willis (1991) and Tallulah Belle Willis (1994).
