Ashton Happens Upon the UK

Ashton Kutcher looked effortlessly cool in his leather jacket and sunglasses at the premiere of What Happens in Vegas in London today. He didn't have Demi on his arm, but his co-star Lake Bell was more than happy to stand in wearing her red carpet matching dress and shoes. Even though Cameron couldn't make it, Ashton still talked about her playful spirit and admitted that she's the real prankster of the two. That's a big statement coming from the creator of Punk'd, but it just makes us all the more excited to see Ashton meet his match on the big screen.
