Steven Tyler, the charismatic 60-year-old frontman for longtime Boston rockers Aerosmith and father of actress Liv Tyler, has reportedly checked himself into Las Encinas Hospital's drug rehabilitation clinic in Pasadena, California, according to TMZ. At press time, a spokesperson for the band could not be reached for comment.

The treatment center is where noted addiction medicine specialist and radio talk-show host Dr. Drew Pinsky practices. It also served as the stage for Pinsky's "Celebrity Rehab" reality series.

While the report wasn't specific, Tyler, who once said, "Four rehabilitation centers for drug abuse later, I've been able to take a long, hard look at my behavior," is said to be receiving treatment for substance abuse.

The news comes just two years after Tyler publicly revealed he'd been diagnosed with hepatitis C, a dangerous liver disease that claims 8,000 to 10,000 lives a year in the United States. Tyler claims he has since cleared the disease from his bloodstream, and while it's not known how he contracted it, users who inject illicit drugs can transmit the disease by sharing needles or other drug paraphernalia.

Of course, Tyler's no stranger to addiction. In the 1970s and early 1980s, "the Demon of Screamin' " was known for his drug and alcohol abuse both on- and offstage, which garnered him and lead guitarist Joe Perry the nickname "the Toxic Twins." Tyler successfully received treatment for his disease and was going on over 20 years of sobriety before this alleged setback.
