Ugh...what is that song??

the guy singing sounds British or something, and some of the lines are like "and she's touching his chest and he takes off her dress" and then something about all in his head and, like, a price I pay...jelousy is mentioned a lot...it's good, but i have no idea what it's called. oh yeah, and Cameron Diaz was singing along (badly) to it in The Holiday, if that helps at all.
