Eva Mendes says the only thing she demands in a man is that he "bathe every once in a while".

The screen beauty plays the unlikely wife of Will Ferrell's out-of-shape desk-bound detective character in new comedy movie 'The Other Guys', but insists she isn't too fussy about the men she dates in real life.

Eva said: "Most women aren't as shallow as men - not as visually shallow. Most of my girlfriends do have qualities they look for in men which are a priority though, like a job!

"I like a guy who is taller than me, so I can wear heels - I'm not particularly tall.

"I also like a man to bathe once in a while, but even that I'm not that insistent on - I do like a bad boy, I like a rock 'n' roller."

Eva - who has dated film director George Augusto since 2002 - also revealed she initially had a hard time working with Will on set, because his improvisational skills kept making burst out laughing.

She explained in an interview with British station Radio 1: "He is a laugh to work with, he's a scream. The first day of working with him was so difficult, because he's a genius of improvisation and I'm not. And I just kept cracking all the time and I quickly had to learn not to. It's not that I had to stop cracking up, but I quickly had to work on my recovery time."
