The former Hear'Say star apparently had X Factor dancer Sarah Robinson thrown out of the Littlewoods catwalk show in Liverpool by security.

Klass split from husband Graham Quinn in April. He was promptly linked with Robinson, but the pair both denied being romantically involved.
"Myleene had no idea Sarah had been booked. She was utterly stunned at her nerve for accepting the gig in the first place," a source told The Mirror.
"Sarah tried waving to Myleene and that was the final straw. Seeing the woman linked to her marriage break-up was all too much so she politely asked that a replacement dancer be found.
"Sarah was in floods of tears afterwards. Myleene spotted her crouched beneath a backstage ironing board, crying and saying, 'I knew this would happen'. It was all rather awkward."
A lawyer for Quinn previously insisted that Robinson had "nothing to do with Graham and Myleene's break-up", while she maintained that they were just good friends.
