The fun-loving Brit admits her man is such a heavy sleeper she can stick beards and Halloween store novelty items all over his face at night after he drops off.
Appearing on The Ellen DeGeneres Show on Monday (14May12), the Serendipity star said, ""Once I found out that I could do the make-up, then it got really crazy and I'd start gluing a proper Pirates of the Caribbean beard on... and then a bullet hole, all this stuff you can get in any Halloween store. It's hours of fun for me.""
And Beckinsale's late night fun is a nightmare for Wiseman: ""He's, like, the shyest person ever so the thought of being the centre of attention is the most horrid idea for him... I wanted him to have to go to work and then have to go to the make-up trailer and say, 'Please can you get this beard off before I have to go on set?'""
But comedienne DeGeneres gave Wiseman a treat on the show when she had a staff member, dressed in a 'This one's for you Len' T-shirt, creep up behind the actress and scare her as Beckinsale was explaining that her husband is not allowed to prank her because, ""I'm kind of more of a nervous wreck than he is. I freak out if he comes into the kitchen just in socks.""
