Las Vegas loser (Ashton Kutcher)

Ashton Kutcher once lost $750,000 gambling in Las Vegas.

The 'What Happens in Vegas' star has revealed he once lost a serious sum of money during a stint in the US gambling capital.

Ashton, 30, said: "I used to bet on sports but I did it as part of a business. I was the front for one of the largest gambling syndicates in the country and I took 10 per cent of the winnings, and that was fun.

"We won $750,000 in three weeks once, and 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."

The US star, who is married to Hollywood actress Demi Moore, also admitted he is something of an entrepreneur when he isn't acting.

He added to Total Film magazine: "I tend to move along several projects at once and jump from thing to thing, which I love doing. I'm not joking - I currently have 12 companies. That includes four restaurants, a bar, a construction company, a bowling alley, a film company, a television company, a digital media company... And I have three films coming out."
