X Factor's Sharon Osbourne has hit out at The Voice UK, branding it boring.
Speaking to us on the red carpet at this week's X Factor press launch, Sharon claimed popstars needed more than to be able to sing.
She sniped: "The Voice is so boring, who wants to see someone sing that looks like a box of frogs? It's boring."
The music manager suggested that this year's new double audition format on The X Factor would help the judges to see who really has the potential to become successful in the charts.
Sharon, returning to the panel after four years, explained: "When I was doing America's Got Talent we did it [the auditions] in the arenas there and I missed the intimacy of doing the small room, so I was happy they brought that back.
"But it's great to put them into the arenas because then you see both sides, the artists change totally from one to another, so it's the perfect combination for me this year."
And Sharon claimed she hasn't watched any episodes of the series since she left back in 2007, saying: "I would never watch when I'm not on, I never watch anything unless I'm on it."
