Tinie Tempah has slammed X Factor judge Louis Walsh during his recent appearance on Never Mind The Buzzcocks.
The London rapper, who hosts next week's episode, made a dig at Walsh as well as N-Dubz.
Tinie told the audience: "Gene Simmons has the longest tongue in the music industry — apart from the one Louis Walsh has up Simon Cowell's ar*e."
Speaking about Lou Redd, Tinie Tampah said: "Lou and his wife played a 20-minute set especially composed for dogs.
"The crowd were licking their b*******, sniffing each other's ar*e, shagging everything that moved and sh*tting everywhere - it was very much reminiscent of an N-Dubz gig."
Meanwhile, Justin Bieber has confirmed that he has recorded a duet with Tinie Tempah.
The pair will perform on an ITV1 special in support of Bieber's news album Under The Mistletoe, which was released earlier this month.
