Christina Aguilera: I'm tough
Christina Aguilera admits she is "kind of a ball-buster".
The fiery judge on the US version of The Voice explained the tension seen on-screen between her and Maroon 5 singer Adam Levine is very much real.
Christina gives as good as she gets and says a challenge will always bring out her fiercely competitive side.
"At the beginning we all got along great. But then we started filming and I was just taken aback - I was not expecting how competitive Adam was. He wants to win!" Christina revealed to UK newspaper The Telegraph.
"And words were tossed round. And if a guy's gonna come and try to get in there and be competitive with me, well, I'm kind of a ball-buster myself."
Over the past two years the star has dealt with numerous dramas in her personal and professional life.
As well as her duties on The Voice, she has faced divorce and recorded a new album. Everything she has been through has made her stronger and Christina is now focusing on being a good mother to her son.
"I live very much in the moment on the show - I don't watch the show back - I feel what I feel, I say what I say, and then I leave it be," Christina continued.
"And I go home and either be with my son [four-year-old Max] or go into the studio and record my own record. I compartmentalise it."
Christina collaborated with Adam and his band on Moves Like Jagger, which topped the charts in 18 countries.
Christina hinted she is the one to be credited for the success of their collaboration.
"I don't think they've experienced that kind of success before," she pointedly finished.
