Martha Stewart to 'Roast' Justin Bieber

— -- Say what?!

Martha Stewart is slated to roast Justin Bieber, 21, later this month for his Comedy Central special that airs later this month.

The mogul will join roastmaster Kevin Hart for the “Comedy Central Roast of Justin Bieber,” which also features Snoop Dogg, Ludacris and Shaquille O’Neal, according to a release on the network's website.

Hart recently dished to MTV on what to expect from the highly-anticipated roast.

"He'll be fine, that's a great friend of mine. I'm not going to be malicious, we'll throw a couple jabs here and there, but it's all about setting the tone," Hart told MTV News over the weekend. "It's all in fun."

Hart added that he's not trying to make the pop singer cry on his 21st birthday on March 30.

"We don't," he said. "[Almost crying] where his face shakes. I don't want to make him cry, I just want to make his face shake. Then, go 'I'm kidding Bieb.'"

The 21-year-old icon has been a good sport about the whole thing, even doing funny promos with him getting egged -- a poke at his trouble last few years.

The “Comedy Central Roast of Justin Bieber” premieres at 10 p.m. EST on March 30 on Comedy Central.
