Cee Lo Green has opened up about his departure from NBC's "The Voice" singing competition.

"It easily and quickly became a job," Green said during an interview with Us Weekly about his role as a coach on the series.

"Very, very obligating... Taxing and tiring... I still tip my hat to Adam and Blake and those guys who continuously do it, but I think I ran my course there just naturally."

The rapper went on to say that he left the show "amicably" and with good memories.

"It really has everything to do with me having the leverage to go elsewhere and be a success as well," he continued.

Green later revealed it was fellow coach Adam Levine who approached him about joining the show in April 2011.

"He called and said, 'Hey man, there's this new show 'The Voice' and I don't really know what it's going to be about, and I don't really want to do any more kind of music shows -- do you think it's cool? If you do it, I'll do it. If you don't do it, I won't do it,'" Green explained.

"And I was like, 'Well, just judging from the premise, the blind auditions' -- It's something that everybody agrees is just really original. It had a great new spin."
