Pop star Rita Ora has revealed she doesn't ''say no to people in everyday life'', which has made her appearance on reality TV show 'The Voice' especially tough.

The 24-year-old pop star is currently appearing as a judge on the BBC reality TV show 'The Voice', and she admits it's especially tough because she struggles to say no to people.

Rita explained: ''It just sucks saying no to an act. It really took some getting used to. ''In the beginning I found it so difficult as I don't say no to people in everyday life.

''I always try to please people and make them happy, even when I know I can't do something. So it was hard for me. ''All the singers are talented. 'The Voice' doesn't have joke acts - these people can sing, so it's really a case of picking out the great ones from the good ones.''

However, Rita - who stars on the show alongside Sir Tom Jones, hip-hop star will.i.am and Ricky Wilson, the lead singer of the Kaiser Chiefs - says the experience has taught her much about herself. She told the Daily Star Sunday newspaper: ''I've learned a lot about myself and the other coaches have taught me a lot too.''
