Insiders have revealed that filming for Sky One TV show, Project Catwalk is often thrown into disarray due to an ongoing feud between show host, Kelly Osbourne and judge Ben de Lisi.

“Kelly and Ben are not the best of friends but they have made no secret of that,” a source told the Daily Star Sunday. “They are both opinionated and not afraid to speak their minds.

“Producers don’t mind a difference of opinion but the tension has started to affect filming. It’s got so bad they have to sit as far apart from each other as possible.”

Series three of the show is just over half way through, and can be viewed on Sky One at 8PM on Thursdays.
