LOS ANGELES: Rocker Steven Tyler has completed 30 days of ‘intensive sobriety treatment’ in a California rehabilitation clinic after publicly acknowledging he was struggling with a painkiller addiction.

The former Aerosmith star, who fell from a stage in South Dakota during a show last summer, is now undergoing a 90-day ‘residential day treatment program,’ according to a statement from the singer’s management company, Tenth Street Entertainment. Tyler has been spotted in the Palm Desert area in recent weeks, leading to speculation he has been at the fabled Betty Ford Clinic nearby. On January 23, he showed up at a Home Depot hardware market and sang two Aerosmith songs over the store’s tannoy system. A source tells People.com, “(He) has privileges to leave the grounds... He was shopping.”

The rocker also showed up at a Palm Desert karaoke bar and belted out Aerosmith ballad I Don’t Want To Miss A Thing.
