Melanie Griffith Checks into Rehab

Melanie Griffith's rep has confirmed that the actress is back in rehab.

"She is there to reinforce her commitment to stay healthy," said her rep Robin Baum. "This is part of a routine plan that was designed between her and her doctors years ago."

According to People Magazine, reports say that Griffith is staying at the Cirque Lodge in Utah. This is the third time Griffith has been to rehab in the recent years.

In 2000, Griffith told the public that she was getting help 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 is married to actor Antonio Banderas and is the most known for her performance 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 previously on her Web site. "My husband and family supported me so much through this journey and continue to do so."
