Maroon 5 heartthrob Adam Levine has responded to speculation about his possible return to 'The Voice' in the USA as a coach. 

When asked by reporters recently if he will sign on for another season with the popular vocal talent TV contest, he teased: "I don’t know. I have to check my schedule."

He was then quizzed on the rumours that suggest Gwen Stefani will step in to replace Christina Aguilera, who is currently pregnant, and explained that she would be a fantastic addition to the show, but didn't confirm or deny her involvement.

The 'She Will Be Loved' hitmaker admitted: "We can neither confirm or deny. She would be a really good addition to the show if she were to be on it, but that’s only a rumor as of now.”

Levine, meanwhile, took to his official Twitter page much earlier today (April 24) and told his followers: "I'm gonna start carrying a mic around just so I can drop it when I do something awesome."
