Melanie Griffith has checked into a rehab facility, her rep confirms to PEOPLE.
"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."
According to reports, the actress, 52, is staying at the Cirque Lodge in Utah. This is the third rehab stint for the actress in recent years.
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, was born into a show-biz family and is perhaps best known for her breakout role in 1988's Working Girl
"Overcoming addictions is tough but it can be made easier if you have someone that can offer support," Griffith wrote on her Web site
once. "My husband and family supported me so much through this journey and continue to do so." – Marla Lehner and Julie Jordan
