The Oscar-winning Milk actor co-founded the J/P HRO Haitian Relief Organization in the wake of the January (10) disaster and has spent months in the Caribbean nation helping to distribute food and medical supplies and build schools and hospitals.
He has also set up a campsite in the country's capital, Port-au-Prince, to help provide temporary housing for an estimated 50,000 survivors left homeless by the tremors.
And Lee has hailed Penn for his hands-on approach to the aid effort after joining the actor in Haiti to witness his work for himself, according to the Hollywood Reporter.
He says, ""Sean Penn doesn't live in the United States any more. He lives in Port-au-Prince.
""That's his life now, trying to get this country on its feet. I have to commend him for that. He's not living in a palace, he's living in a tent. I know because I slept three nights there. It's a tent-tent. He's put in his dues and time to speak about Haiti.""
