Wyclef Jean accused Irish American actor, Sean Penn, of doing coke during a concert over the weekend.

Jean, a onetime Haitian presidential hopeful said "I got a message for Sean Penn: Maybe he ain't see me in Haiti 'cause he was too busy sniffing cocaine."

Sean Penn had once said that Jean was a "non presence" in Haiti.

A representative of Penn releases the following statement: "Mr. Jean is clearly unfamiliar with the physical demands put upon volunteers in Haiti. As aid workers there, the notion of depleting the body's immune system thru the use of illicit drugs is ludicrous. More specifically, J/P Haitian Relief Organization (a.k.a. JPHRO) has a ZERO tolerance policy for any and all illegal drugs. As the leader of this organization, Sean Penn has not only set this policy, but adheres to it. That Mr. Jean would make such a false accusation is reckless and saddening, but not surprising."
