Osbourne: 'I tell Piers to shut up'

Sharon Osbourne has criticised her America's Got Talent co-star Piers Morgan for having a huge ego.

The reality TV judge claimed that Morgan is obsessed with talking about his victory on the US celebrity edition of The Apprentice.

"I tell him to shut up," she told The Sun. "Nobody cares about The Apprentice, yet we have to hear about it, over and over again."

She joked that Morgan would require "a roadie to carry his ego".

Fellow judge David Hasselhoff is also apparently unhappy with Morgan's behaviour on the show.

When asked about his co-stars, he told Radio 1: "Sharon's great. Piers Morgan? No comment."
