The National Enquirer is claiming Mel Gibson is struggling with his bid for sobriety. They report Gibson walked into an AA meeting near his Malibu home, stumbled over a row of seats and crash-landed atop them. "He was falling, tripping and clearly off balance," said a source. "It was an embarrassing moment." Later that evening, Mel stumbled into a petite woman, knocking her off balance. "And he didn't even apologize!" said the source. "He looked so out of it."
