This weekend's Comedy Central roast of Justin Bieber was pretty harsh. There were even reports the newly minted "King Joffrey of pop music" shed a couple of tears.

While roasts are supposed to push the envelope, roaster Ludacris believed some of the jokes about his late friend and Fast and Furious co-star Paul Walker went too far.

Luda was seen grimacing when roast master Jeffrey Ross made this joke:

"‘Move bitch, get out of the way,’ that’s what Paul Walker should have told that tree," Ross joked. When the audience groaned, he added: “Too soon? Too fast? Too furious? Give me a break people, I’m trying to save this kid’s life."

"Just this past year, Justin got arrested for drag racing. Unfortunately, it wasn’t with Paul Walker. What? He’s doing great! He’s got a movie coming out!"
