X Factor are facing some trouble with Television watchdogs OFCOM after blurring Sharon Osbournes pink Motorolla Razr on a recent show.

The X Factor, which is sponsored by Nokia, prominently displayed Louis Walsh’s Nokia phone on screen, but when the time came to show Sharon chatting on her mobile, it was blurred beyond recognition.

This is despite Ofcom rules that programmes must not be “distorted for commercial purposes” by sponsors.

One show insider said: “Nokia has tried everything. She won’t budge.”

A spokeswoman for the show said: “We are aware of all regulations and work within them.”

Nokia, whose deal is worth £10million, said: “All the mobiles in the programme are used at the owners’ choice.”
