London, Feb 15

"Twilight" star Robert Pattinson was left squirming during a steamy photo shoot for an upcoming men's magazine as he was surrounded by naked female models.

The actor appears on the cover of America's Details magazine and features in a series of sexy shots with nude women. But instead of enjoying being in the company of the beautiful models, the actor insists he was a nervous wreck because he didn't know where to look or what to say, reports contactmusic.com.

"But I wasn't exactly prepared. I had no idea what to say to these girls. Thank god I was hungover," said Pattinson.
