Comedy Central is known for its amusing roasts and Justin Bieber is the latest star to get roasted.

Is Selena Gomez Stewing Over Justin Bieber's Assumed Hook Up With Mily Cyrus?

The Comedy Central Roast of Justin Bieber featured many celebrities including Martha Stewart who possibly stole the show with her edgy and dirty jokes, which even got the Comedy Central Twitter wondering if her portion of the roast contained "the edgiest joke".

What did Stewart say that could be deemed "the edgiest joke"?

Did Martha Stewart Hit On Josh Murray?

Well, in the first clip below, Stewart said, "As we all know, Kevin [Hart] is one of the biggest movie stars in the business right now and he deserves it. He struggled for years. When he finally got his first big paycheck, he spent $150,000 on a watch. I forget the term for that. It's not 'African American rich.' It'll come to me."

That led to shocked expressions in the audience and a hysterical Hart and a hysterical Bieber.

"Justin, you know the word," Stewart then added.

The businesswoman then went into a couple more jokes about Shaquille O'Neal and Ludacris. The one involving Ludacris was quite dirty and totally tops her quite clean joke in the tweet she made on March 6 about the kind of roast Bieber likes.

Stewart even talked about making brownies with Snoop Dogg, which can also be seen below.

Bieber haters and lovers alike believe Stewart nailed the roast perfectly.

One Twitter user said she should be the "MVP" of the roast.

Another user claimed, "You were by far the highlight," in a tweet to Stewart.

It definitely sounds like Stewart stole the show!
