"Fifty Shades of Grey" cast member Rita Ora recently admitted that she is worried about people's judgment towards her work as coach for "The Voice UK" season 4. Calvin Harris' ex-girlfriend also said that Will.i.am convinced her to join the BBC show as a judge.

The 24-year-old "I Will Never Let You Down" singer admitted to The Daily Star, "I've been getting so nervous about what people will think of me. People have a different perception of me compared to what I'm actually like."

She said that being a coach for "The Voice UK" season 4 is just as hard as being on a stage as a contestant, Mirror reported.

"I'd almost rather be on stage for three hours straight singing and sweating than be in that chair for longer than seven hours," said "Fifty Shades of Grey" cast member Rita Ora.

Calvin Harris' ex-girlfriend also revealed that "Black Eyed Peas" member Will.i.am convinced her to join "The Voice UK" Season 4.

"We've been close friends for a while and I was like, 'Yo! They've asked me to do The Voice and I don't really know what to do.' And will.i.am said, 'If you do it, you are going to give these people something," Rita Ora explained.

The chart-topping "Black Widow" singer claimed that she's trusting Will's honesty a hundred percent.

Her co-judge Kaiser Chiefs' front man Ricky Wilson also commended the "How We Do" singer for having a feisty image and the character of holding her own against the other panelists, Express said.

"I hope she's a bit mischievous because we've already got one mischievous one on the end there [will.i.am] and I think we need another one to counteract that," the front man even joked.

Aside from her debut on "The Voice UK" season 4, this year is also big for Calvin Harris' ex-girlfriend as she is one of the cast members of the highly-anticipated film "Fifty Shades of Grey." Rita Ora will play Mia Grey.
