Reality television bad boy Jason Wahler has falled off the wagon after a stint in Celebrity Rehab, Breaking Celebrity News has exclusively learned.

"Things were going so well for Jason until last week," said a source, close to the former Laguna Beach star.

Last week, Wahler was photographed at Hollywood hot spots Boa and Katsuya.

"He went out three nights in a row last week," added the source.

"At one stage last week, Jason pleaded to move in with a close friend at her Los Angeles home, who also went through Dr. Drew's television rehab.

"But his behavior was too erratic and it's clear his sobriety is no longer important to him."
