Stars including rapper Snoop Dogg and lifestyle guru Martha Stewart are set to poke fun at Justin Bieber during the pop star's upcoming comedy roast.

The Baby hitmaker is to become the butt of all jokes at the Comedy Central Roast, which is set to be filmed this month (Mar15), and the newly-announced line-up includes unlikely duo Snoop Dogg and Stewart.

The roast, which will be hosted by comedian Kevin Hart, also features rapper/actor Ludacris and basketball legend Shaquille O'Neal, along with comedians Hannibal Buress, Chris D'Elia, Natasha Leggero and Jeffrey Ross.

It is not known if Seth Rogen will be a surprise addition to the cast after Bieber launched a high-profile campaign to have him added.

The show is expected to be taped on 14 March and air in the U.S. on 30 March (15).
