Bruce Willis has responded, somewhat angrily, to rumours that he and actress Drew Barrymore are dating after he was photographed kissing the actress at a party.

Bruce, promoting his new film �Live Free or Die Hard� (aka �Die Hard 4�), said in an interview: �Drew and I are old friends. I hadn't seen her for a long time, and I gave her a kiss.�

�I'm a single guy, and I'm having a hard enough time in the world of romance without somebody giving me shit for kissing Drew�.
