The 30-year-old actor – who is married to Demi Moore – partied at hot Los Angeles nightspot Apple with a group of pals including his ‘That ‘70s Show’ co-star Wilmer Valderrama on Tuesday night (04.11.08).

A source said: “Ashton was mingling with his friends at his booth. I see Wilmer out all the time at parties with girls and drinks, but I haven't seen Ashton out in forever. He was having a really good time.”

Ashton spent the evening joking with friends and drinking Patron Tequila Silver and appeared happy and relaxed.

The actor recently revealed his wild past included losing $750,000 while gambling in Las Vegas.

Ashton said: “I used to bet on sports but I did it as part of a business. We won $750,000 in three weeks once, then I went to Las Vegas and gambled it all away, so probably not the most sensible thing to do with all the money. "People win and they go back and lose, so I think your net gain in Vegas is always at a loss. But nothing stays in Vegas. Only your money and maybe your virginity."
