Sharon Osbourne's return to the X Factor has been confirmed.

The outspoken music manager was a popular fixture on the judging panel until 2008 when she left for pastures new.

She will line-up alongside returning judges Louis Walsh, Gary Barlow and Nicole Scherzinger.

In a statement, Osbourne said:

"I couldn't be happier about coming back for the 10th anniversary of X Factor. I can't wait to give Gary Barlow a big hug, sit next to the gorgeous Nicole, and of course throw water on dear Louis. Yay!"

Show supremo Simon Cowell meanwhile added: "Three words I never thought I'd say....Welcome back Sharon!"

Host Dermot O'Leary commented: "We've got a great line-up this year, and Mrs O is always a riot and a brilliant mentor, it should be fun."

Osbourne replaces outgoing judge Tulisa, who announced her departure on Tuesday (May 21).
