Giorgio Armani will partner with actor Sean Penn to raise money for Haitian charities at the Cannes Film Festival.

Armani is sponsoring Penn's fundraising dinner Haiti: Carnival in Cannes, which Penn will host on Friday with model Petra Nemcova. The dinner's proceeds will be donated to Penn's Haitian Relief Organization, Nemcova's Happy Hearts Fund, and Artists For Peace and Justice.
