Aerosmith’s Steve Tyler has checked himself into substance abuse rehab.

The hard rocking Tyler had remained sober for 20 years after getting treatment back in 1986.  Tyler and bandmate Joe Perry were known as The Toxic Twins for their heroin and substance abuse which caused havoc with Aerosmith’s schedule.

Tyler is reportedly at the Las Encinas Hospital Rehabilitation  -where former Hollywood madam Heidi Fleiss, Sebastian Bach and pop star Aaron Carter will suffer for sobriety on new reality TV show Celebrity Rehab.   
Only his publicist knows whether or not Tyler will "Walk this Way" onto the celeb-detox show as well.
