Melanie Griffith is back in rehab, her rep confirms to PEOPLE.
According to reports, the actress, 52, is staying at the Cirque Lodge in Utah. This is the third rehab stint for the actress.
"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."
In 2000, Griffith released a statement that she was seeking treatment for a drug problem.
"My doctor has referred me to the Daniel Freeman Hospital to step down from the prescribed medication that I have been taking for a neck injury," she said.
Griffith, who is married to Antonio Banderas, is best known for her role in 1988's Working Girl.
