This past Saturday - March 14 - celebs gathered for the Comedy Central Roast to prey on Justin Bieber with their words, but a few of the so-called jokes may have gone too far.

The 21-year-old pop singer wasn't the only one at the receiving end of the hurtful comments. His famed ex Selena Gomez was thrown into the loop too, but the most surprising target was the late Paul Walker, who was killed in a car crash in November 2013. He was 40 years old when he died.

Walker was referenced a time too many while his "Furious 7" costar Ludacris listened and obviously showed discomfort.

"'Move bitch, get out the way!' is what Paul Walker should've told that tree," comedian Jeff Ross said. "Too soon? Too fast? Too furious?"

Ross referenced lyrics to Ludacris' 2001 hit "Move Bitch," and the rapper was "deeply upset" by the remark, according to Page Six.

If those words weren't enough to upset the crowd, "Saturday Night Live" newcomer Pete Davidson also contributed to Ross' poor taste in humor.

"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!" he said.

A source close to Ludacris said that the comments "were in absolutely poor taste and silenced the audience, leaving many upset guests - especially Chris, as Paul was like a brother to him, on and offscreen." 

The 37-year-old rapper wasn't the only one who was bothered by the comedians' insensitivity. A rep for Comedy Central said that all jokes about Walker will be removed for the March 30 telecast, Us Weekly reported.

"Roasts often push the limits of good taste," the rep said in a statement to Page Six. "Sometimes the line is discovered by crossing it. The Paul Walker references will not be in the telecast."
