The Forget You singer faced felony charges of sharing ecstasy with an ex-girlfriend, who had accused him of slipping her the drug during a dinner date in 2012 - and then having sex with her.

He was subsequently sentenced to three years of probation and 45 days of community service as part of a deal with prosecutors, and as a result, he was forced to step down as a mentor on The Voice after four seasons.

But now, as he prepares to release his new album, Heart Blanche, next month (Nov15), Green is hoping to make a return to the reality show to coach aspiring singers as part of his comeback.

"I've talked very possibly about doing The Voice again," Green told Billboard. "So I just kind of put that out there, wishful thinking, kind of willing it. Because I would love to do it again."

"It was a very redefining moment in my personal and professional life," Green said of his felony case. "I feel really strong and really confident about this album and going forward. And I'm so grateful that you yourself, and everyone who just may happen to witness this particular interview, have my deepest, sincerest apologies for any inconvenience, any ignorance, any ill will, anything. I'm just glad that it's behind me now. I'm so glad for it."

Green was part of the first group of The Voice coaches when the show premiered in 2011. He joined Adam Levine, Blake Shelton and Christina Aguilera, who are all very much part of the programme. Levine and Shelton are judges on the current ninth season, while Aguilera will return for the 10th season next year (16).
