The Wanted's guitarist Tom Parker is definitely not a fan of Christina Aguilera.

In a recent interview with New York's radio station NOW FM, Parker recalled meeting Aguilera on the set of The Voice after the band's performance.

Tom tells NOW FM:

    "She's a total b*tch. She might not be a b*tch in real life, but to us, she was a total bitch. She just sat there and didn't speak to us. Wouldn't even look at us."

His band mate, Siva Kaneswaran added, "She was quite rude. Who does that?"

Yikes! Perhaps Xtina just wasn't having a good night.
