Justin Bieber Roast Sneak Peek: Snoop Dogg Makes A 'Mom' Joke, Of Course (VIDEO)

The day of the Justin BieberComedy Central roast is almost upon us.

We've read the best of the roast jokes and we've seen pictures from the roast, but we've yet to see a clip.

The good folks at Comedy Central sent through a short video of the show, featuring rapper Snoop Dogg taking a shot at -- yep -- Justin Bieber's mother. He also takes the opportunity to make fun of Usher. Would you expect anything else?

This is just a taste of what's to come.

The "Comedy Central Roast of Justin Bieber" airs Monday, March 30 at 10 p.m. ET/PT on Comedy Central.
