Former teen idol Leif Garrett, who's perhaps better known for his shirtless pin-up posters than for his singing career, has run into a bump on the comeback trail following a drug-related arrest.

The singer pleaded not guilty to possession of heroin and cocaine in a Los Angeles courtroom last Thursday following his arrest on June 29. The 37-year-old singer reportedly asked an undercover narcotics officer for crack during a sting operation. Garrett was subsequently searched, and the drugs were allegedly found on him. Nine other people were also arrested in the sting.

Although Garrett's drug problems have been well documented, most recently in an episode of VH1's "Behind the Music," he does not have a criminal record. Garrett is free on $10,000 bail and is scheduled to reappear for a hearing on August 13.

Garrett has been attempting a comeback as of late with his band Godspeed. The trio released an EP in June featuring two original tracks and a cover of the Kinks' "Lola" on

Garrett's own Tongue and Groove Records. Guitarist Zim Zum (formerly with Marilyn Manson) appears on the disc, as does Dave Navarro, who guests on piano.

According to the APB News service, the singer's attorney asked that his client be allowed to enter a drug treatment program, which could lead to a dismissal of the charges. The lawyer told APB that he might also fight the charges because the case against Garrett was "not at all clear."

Garrett catapulted to fame and fortune in the late '70s as a young teen actor and singer and released marginally successful covers of songs by the Beach Boys, Dion, and Paul Anka, and he had one Top 10 hit, 1979's "I Was Made for Dancing." He stopped recording in the early 1980s, and virtually dropped out of sight, although he was saved from total obscurity over the course of the decade by a handful of minor TV and movie roles.
