ENTERTAINMENT: David Arquette Checks Into Rehab!

David Arquette has checked into rehab for treatment of alcoholism and "other" issues. He made the move to the Betty Ford center because he believes it's "the right thing to do for his family," a source tells TMZ. "He's in there for drinking and depression, not hard drugs," says a representative. The news comes two months after his split with wife Courteney Cox and increasingly erratic behavior. "When I drink, I become a maniac," he told Howard Stern last month.
