Adam Levine
The Maroon 5 frontman realised how unpleasant it must have been for Christina Aguilera when the rest of the ‘The Voice’ judging panel kept farting in front of her, which at the time in 2010 consisted of country crooner Blake Shelton, Cee Lo Green and himself.
Speaking in 2012, Adam joked: "I honestly just recently started realizing that [she's] surrounded by three dudes all the time, and that has to be something of a pain in the a**. But we stopped farting in front of her!"
