But the singer and fashion designer 44 years said that joining the men's team coaches in the talent competition 'The Voice' NBC has tested his tolerance level.
"I must say that Adam (Levine) actually has, you know, raised the bar. It is mean and spoiled and dirty and nasty and really has no filter. It's just shocking," Stefani joked
in a recent interview.
The Maroon 5 frontman does not regret anything.
"I do not mind saying things because people anyway finds a way to bother with anything you say," he said. "So I prefer to be disgusting and humorous and eccentric to be boring."
The seventh season of 'The Voice' premieres with Levine, the Queen of Country Music Blake Shelton and Stefani and Pharrell Williams beginners and coaches.
Levine, who recently married Victoria's Secret model Behati Prinsloo, warned that this could be his most outrageous season.
"He probably has even less filter now that I'm married I could never hit or offend the sensibilities of my wife, because she's like me," he said.
Pharrell Williams, meanwhile, said working with the contestants was a "magical" experience and is taking it seriously.
