(Cover) - EN Showbiz - The Wanted believe that "manners cost nothing."

The British boyband - comprising of Max George, Siva Kaneswaran, Jay McGuiness, Tom Parker and Nathan Sykes called singer Christina Aguilera a "total b***h" on 92.3 NOW radio in New York City last week.

TMZ reports that the group is remorseful for making the comments, but feel they were founded.

"We shouldn't have said it, to be honest with you," Tom told the website. "We just think manners cost nothing, you know what I mean?"

The Wanted came in contact with Christina while they appeared on American TV show The Voice.

"She's a total b***h," Tom previously recalled on the radio station. "She might not be a b***h in real life, but to us, she was a total b***h. She just sat there and didn't speak to us. Wouldn't even look at us."

Tom's sentiments were supported by the whole group.

"She was quite rude," Siva added. "Who does that?"

Christina has been embroiled in notoriously public feuds with Kelly Osbourne in the past for calling the presenter "fat". (C) Cover Media
