Melanie Griffith has entered rehab. Her rep says: " She is there to reinforce her commitment to stay healthy," says her rep Robin Baum. "This is part of a routine plan that was designed between her and her doctors years ago." I'm wondering if this is a way to re-enforce sobriety? It seems like a smart idea if someone has a history of falling off the wagon. Best of luck to Melanie Griffith.
