Melanie Griffith Checks Into Rehab

Melanie Griffith, 52, checked herself into Lindsay Lohan's former joint, the Cirque Lodge in Utah. Her stay is reportedly "routine."

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

This isn't the first time the 52-year-old mother of three -- and wife to Antonio Banderas -- has gone to rehab.

The actress sought treatment in 2000 for an addiction to painkillers, which she started using after suffering a neck injury. She also spent time at a facility 1988 to battle alcoholism and cocaine addiction.
