Christina Aguilera blasts Simon Cowell

Christina Aguilera called Simon Cowell a ''d**k''.

The singer is currently a mentor on 'The Voice' and admitted she doesn't watch rival reality TV shows such as Simon's 'The X Factor' and 'American Idol' which he previously appeared on but once saw a clip of him on the latter and thought he was needlessly mean to the contestants.

Speaking at the Billboard/Hollywood Reporter Music Conference, she said: ''I've not actually seen a full episode of any of the other music shows. I saw the commercials early on of 'American Idol' of Simon being a d**k. I was like, 'Man, that's not what it's about!' I didn't want to treat people like that. I wanted to do 'The Voice' to show that we can be positive. We don't have to knock people down.''

Christina also claimed she has to be tough to survive in the music business because people will try to walk all over her.

She explained: ''It's hard being such a powerful woman in the business. I'm known for not always being warm and fuzzy, because you'll just get bulldozed over. You learn to put up this little protective shield, but it's because of something. In my music, I come off as being very open about being insecure, vulnerable and sensitive sometimes. Then I'll go onstage and be this powerhouse force to be reckoned with.''
