Melanie Griffith perhaps best known for her breakout role in 1988’s Working Girl,has checked back into a rehab facility, making this her third known stint. Griffith, 52, who is married to Antonio Banderas, has battled addictions to drugs and booze since she was a teenager and is reportedly staying at the Cirque Lodge in Utah this time. “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.” But Star Magazine inside sources say that she has fallen off the wagon again and her husband of 13 years, Antonio Banderas, has made an ultimatum that she pull herself back together or else. “The reason Melanie checked in was her husband was demanding that she get clean and sober,” a source tells Star. “He told her that if she didn’t get the help she needed it would be the end of their marriage.”
