Justin Bieber has himself asked Comedy Central to be roasted to celebrate his 21st birthday as he wants to make a public declaration he's screwed up a lot in the past, but he's figured it out and has changed for the better.
The 20-year-old singer thinks that if the comedy network channel will make fun of him it will act as a therapy, TMZ.com reported.
It has also been reported that the 'Baby' hitmaker seems to have changed over the last 4 months and people have also observed a radical change in the singer's behviour.
