Los Angeles - Ludacris has been left "deeply upset" over comments about his late co-star Paul Walker during Justin Bieber's Comedy Central roast.
The Act A Fool hitmaker was left reeling after Jeff Ross used both the title of his song Move Bitch and referred to his Fast and the Furious co-star's death in a car crash in November 2013 as he slated the 21-year-old singer, according to the New York Daily News.
Jeff said: "Move bitch, get out of the way, is what Paul Walker should've told that tree. Too soon? Too fast? Too furious?"
Fellow comedian Pete Davidson, who also took part in the roast, said: "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!'

A source close to the star - whose real name is Christopher Brian Bridges - said: "The jokes were in absolute poor taste and silenced the audience, leaving many upset guests - especially Chris, as Paul was like a brother to him, on and off screen."
Following the negative response to the jokes, Comedy Central has pulled the quips from the roast's broadcast.
A representative said: "Roasts often push the limits of good taste ... sometimes the line is discovered by crossing it. The Paul Walker references will not be in the telecast."
