Cee Lo Green says he is prematurely ending his gig as warmup act on Rihanna's North American tour to focus on his new album and his television commitments.

Anne Watkins, a representative of Green's management company, told The New York Times that Green's plate has gotten so full this summer that "he feels he wouldn't give (Rihanna) fans the show they deserve.

"He always puts 100 percent into his work," Watkins said in a written statement.

Watkins denied the decision had anything to do with the recent dust-up over some reputedly homophobic statements Green made over Twitter in regards to a review panning his show.

The Hollywood Reporter said Saturday that Green, who apologized for his Twitter jibes, joined Rihanna earlier this month for a 17-city tour of the United States and Canada that runs through mid-July. He also is slated for appearances on the NBC talent competition "The Voice."

There was no immediate word on who would replace Green on the tour.
