Pop hunk Justin Timberlake watched with delight as an orgy unfolded before his eyes at HUGH HEFNER'S PLAYBOY MANSION.

According to British tabloid NEWS OF THE WORLD, the CRY ME A RIVER singer and his gorgeous girlfriend Cameron Diaz didn't join in the romps, but stayed to ogle the action.

Playboy bunny ZOE GREGORY-PAUL says, "Justin was clearly enjoying what he was seeing. What was going on there was hot.

"The grotto is the perfect place to make love - there are three sofas, as well as a jacuzzi and pool with a waterfall.

"Justin was there with his mates and he asked me, 'Can you get a group of girls to come down here for us - we want some action, too?'

"No one bats an eyelid when they see stars having full sex at a Playboy party. Justin just kept on watching. I heard he stayed down there for most of the night.

"I've seen Cameron Diaz there too. But she doesn't take part."
