Two jokes referencing the late Paul Walker during Justin Bieber’s Comedy Central roast Saturday night left Ludacris “deeply upset,” a source close to the singer says.

During his time at the podium, Jeff Ross used the title of a Ludacris song.

“‘Move bitch, get out of the way!’ is what Paul Walker should’ve told that tree. Too soon? Too fast? Too furious?”

And then Pete Davidson made another.

“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 joked to the crowd.

But Ludacris, a “Fast and Furious” co-star of Walker’s, didn’t find the jokes funny.

Walker died in November 2013 from injuries he sustained when the Porsche he was a passenger that was going over 100 mph wrapped around a light pole and burst into flames. He was 40.

A representative for Comedy Central said that although these roasts are designed to have jokes like these and “push the limits of good taste,” the Paul Walker jokes will not air during the telecast March 30. (RELATED: Here Are The HARSHEST Jokes Made During Justin Bieber’s Roast)

“Sometimes the line is discovered by crossing it,” the rep said.
