A little while ago we reported on billionaire Tom Crist who won a $40 million lottery jackpot - and astoundingly gave it all away.

But it's not only the super-rich who have tried their luck and played lotto.

These 14 celebrities will be familiar faces to most of the world. Their dirty secret? They all confess to have played the lottery at some time.

Matt Kemp, the baseball star who plays in the NBL has an annual salary of $21 million, as well as the millions he has earned in his previous years.

Celeb Paris Hilton bought 1500 entries in Italy’s national Superenalotto game in 2008.

It’s not the first time Paris has played this game. She justified herself by saying: "If I won, I would donate 10 percent to charity benefits."

Actor heartthrob George Clooney made a block purchase of 1,000 SuperEnaLotto tickets, hoping to hit the jackpot so he could donate the entire sum to the people of Haiti for earthquake relief.

Actress Elizabeth Hurley, a good friend of George Clooney, also bought 500 SuperEnaLotto tickets to help the Haiti earthquake relief.

She donated her prize money, €120,000 in secondary prizes, to the construction of schools in Malawi, Africa.
