Sean Penn officially named an ambassador to Haiti, report says

Sean Penn was officially made an ambassador at large for Haiti for his relief work for the country, which is still reeling from a devastating earthquake two years ago.

Penn was offered the job Saturday night by Haitian foreign minister Laurent Lamothe at the Cinema for Peace benefit at the Montage Hotel in Beverly Hills, Calif.

"I do accept," Penn said, adding that it would be useful to "change being called 'Hey you [bleep]' to 'Hey Mr. Ambassador.'"

The event, which raised $5 million for Haiti, was attended by an A-list crowd including Demi Moore, Melanie Griffith, George Clooney, Julia Roberts, Orlando Bloom and Mel Gibson.

During the auction, singer Damien Rice spent $475,000 on Bono's guitar, while Roberts' husband, Danny Moder, bid $50,000 on a trip to Haiti with Penn.
