London: Teen pop sensation Justin Bieber is reportedly heading for a stint in rehab after his recent wild partying antics.
The `Baby` hitmaker`s partying behaviour is said to be getting out of hand when his recent birthday venue smelt of marijuana after he left the bash, reported Daily Star.
There were pictures also which showed the 19-year-old singer stumbling around London drunk and topless.
Bieber continued his 19th birthday celebrations in London by twice getting mobbed by fans and photographers. One club even refused him entry for being under-age.
