Damon, Affleck, Confirmed Africa Charity Poker

Hollywood stars Matt Damon and Ben Affleck have confirmed to participate in the World Series of Poker's Ante up for Africa charity tournament in Las Vegas on July 3.

The pair previously competed in the inaugural event in 2007, along with 200 other celebrities and poker pros.

Since then, the tournament, which was created by Don Cheadle, Norman Epstein and poker pro Annie Duke, has gone from strength to strength, with its ability to attract celebrities as its drawcard.

Duke said the event organizers were "very excited" to have Damon and Affleck compete in the event's fourth instalment, saying: "We look forward to hearing from more big names in the gaming and entertainment industries as they come on board to give their valuable time and energy and bring attention to the dire crisis taking place in areas in Africa like Darfur."

Ante up for Africa specifically raises funds for Africa-related charities such as the Enough Project, which works to prevent genocide. In the past it has also contributed to other organizations such as Not on our Watch and the International rescue Committee, with players asked to donate half of their winnings from the tournament back to the charities.

Other celebrities to have participated in the past include former basketballer Charles Barkley, former boxing champion Mike Tyson, and Seinfeld star Jason Alexander.

This year's event, which will be held once again at the Rio All-Suite Casino, will no doubt attract just as many high-profile celebs.
