Toxic Twin In Trouble

After allegedly being drug-free for 20 years, Steven Tyler has reportedly signed himself into Las Encinas Hospital in Pasadena, Calif., for substance abuse rehab.

Radio talk-show host Dr. Drew Pinsky calls the hospital home and it’s also the stage for his "Celebrity Rehab" reality show.

The Boston Herald noted that some friends of the Aerosmith frontman blame his relapse on his two-year relationship with 30-something former Clear Channel tour accountant and party friend Erin Brady – while others say Tyler’s health problems over the past few years may have led to an addiction to painkillers.

Two years ago the 60-year-old rocker announced he’d been diagnosed with Hepatitis C, a liver disease that claims 8,000 to 10,000 lives per year in the U.S. and can be transmitted by users who share needles and other drug paraphernalia. According to MTV.com, it is not known how Tyler contracted the disease but he claims he has cleared it from his bloodstream.

A few weeks before the rehab announcement was reported by TMZ, Tyler participated in a benefit concert for MusicCares’ MAP Fund, which helps addicted musicians get treatment.

Tyler sang "Mama Kin" and presented an award to a sober Slash. The concert also featured a tribute to drug counselor Bob Timmons, who died in March and used to go on tour with Aerosmith in the ’80s and ’90s.

The paper noted that Timmons went on tour with the band during the time it was managed by Tim Collins, who helped the members get off drugs – but was fired in 1996.

Before cleaning up, Tyler and lead guitarist Joe Perry’s drug and alcohol abuse on and offstage during the 1970s and early 1980s earned the duo the nickname "The Toxic Twins."
