Rita Ora confirms she's leaving The X Factor

The singer, who joined the show last year, tweeted: "I had a ball on The X Factor last year and will miss the team.

"@simoncowell can't wait to work with you again... I'll be round for dinner soon. Thank you for the experience & love X"

Rita took on the role after moving from The Voice UK, which is moving from the BBC to ITV.

The singer mentored the girls category and went on to win the show with her act, Louisa Johnson.

In a statement ITV told Newsbeat: "Rita brought a great energy to the show last year and did a brilliant job mentoring the girls' category, leading Louisa to victory.

"We wish her all the best with her music and film plans for the rest of the year."

Her decision means Simon Cowell is the only judge left from last year's line-up.

It's after Cheryl Fernandez-Versini and Nick Grimshaw also announced they wouldn't be returning for the new series.

Confirming the news on his Radio 1 Breakfast Show back in February, Nick Grimshaw said he quit the show and wasn't fired.

"I did love it and it's not a diss to the show. It's a great show and I loved it. But it's definitely a once in a lifetime style thing," he said.
