Adam Levine has "stopped farting in front of" Christina Aguilera

The Maroon 5 singer who mentors on the competition alongside the blonde beauty, Cee Lo Green and Blake Shelton decided to improve his manners when he realised the 'Ain't No Other Man' hitmaker is surrounded by males when she shoots the programme.

He told Rolling Stone magazine: "I honestly just recently started realising that you're surrounded by three dudes all the time, and that has to be something of a pain in the ass. We stopped farting in front of her!"

Christina who recently worked with Adam on Maroon 5's 'Moves Like Jagger' hit - admits she has to be a "pretty strong girl" to put up with the "crazy" testosterone-filled environment during filming.

She added: "You have to be a pretty strong girl to stay up in the mix with the guys. It's a lot. It's a crazy locker-room kind of situation."

But the 31-year-old star finds the show which sees mentors pick contestants without seeing them in order to judge them purely on their vocal ability is a "very good outlet" for her to share "highs and lows" about her life.

Christina - who has son Max Liron, three, with ex-husband Jordan Bratman explained: "You have got to be a strong, powerful, very confident woman. Being in a position to coach these young women, I am happy to be able to share that with them and share my highs and lows. Being on the show, it's a very good outlet."
