Rita Ora leaves 'The X Factor' after one season

LONDON, May 11 (UPI) -- Rita Ora is quitting The X Factor after just one season.

The 25-year-old British singer confirmed she won't return to the ITV reality competition in a tweet Tuesday after serving as a judge on Season 12 in 2015.

"I had a ball on @TheXFactor last year and will miss the team," Ora wrote before addressing series creator Simon Cowell, "@simoncowell can't wait to work with you again... I'll be round for dinner soon. Thank you for the experience & love."

The "Radioactive" singer served as a judge with Cowell, Cheryl Fernandez-Versini and Nick Grimshaw. She mentored the Girls house with Meghan Trainor as her assistant, coaching contestant Louisa Johnson to victory.

"Rita brought a great energy to the show last year and did a brilliant job mentoring the girls' category," ITV said in a statement to the BBC. "We wish her all the best with her music and film plans for the rest of the year."

Fernandez-Versini and Grimshaw previously departed the series, leaving Cowell as the sole judge thus far for Season 13. Nicole Scherzinger, who served as a judge on Seasons 9 and 10, is rumored to be returning to the panel.

Ora previously served as a coach on The Voice U.K. Season 4. The singer released her debut studio album, Ora, in 2012, and has her second record in the works. She will reprise the role of Mia Grey in Fifty Shades Darker, out Feb. 10, 2017.
