Justin Bieber is going to be the star of his own 'Comedy Central Roast' to mark his 21st birthday.

The pop star has been chosen to be the butt of the channel's jokes for a TV special that will air in March.

Justin had been asking Comedy Central to mock him for years but they previously decided there wouldn't be enough material on him for jokes, but following his eventful 2014 producers believe the time is right.

The broadcaster announced the news in a statement, which said: ''Justin has been asking us for years to roast him so we kept telling him to create some more material and we're thrilled he listened.''

Radio presenter Ryan Seacrest took to Twitter to share his excitement at the news, posting: ''Yes I got confirmation @JustinBieber is getting roasted by @ComedyCentral in march ... love u justin but it's time lol #BieberRoast (sic)''

The 'All That Matters' hitmaker is thrilled his antics, which have included egging his neighbour's house, arrests for driving offences and his on/off romance with Selena Gomez, have earned the right to be roasted.

Justin tweeted: ''For years I have wanted Comedy Central to roast me. They said only if I provided them w/ more material so for a year now I have worked hard ... Finally after all that hard work for my 21st bday it's happening. Thanks @RyanSeacrest & @ComedyCentral for the announcement. Let's do it :) ... Lol. #BieberRoast (sic)''

Justin reaches the milestone age on March 1 and the Comedy Central roast will be filmed on March 7 airing later in the month.

Previous Comedy Central roastees include Charlie Sheen, Pamela Anderson, James Franco and Donald Trump.
