Aerosmith frontman Steven Tyler checked himself into a Pasadena, California drug rehabilitation clinic. The 60 year old Tyler was admitted into Las Encinitas Hospital's treatment facility, according to TMZ.

The hospital should be familiar to viewers of VH1's recent 'Celebrity Rehab' series. Las Encinitas is home to the practice of that reality show's host Dr. Drew Pinsky.

In his four decades out in front of Aerosmith, Tyler is no stranger to drug treatment. He once revealed that he has had four trips to rehab. Now, with his fifth trip, Tyler has broken a twenty year run of sobriety.

In 2006, Tyler revealed that he had contracted Hepatitis C, a dangerous liver disease known to plague intravenous drug users, but had cleared it from his body.
