Rihanna has lost the opening act of her LOUD tour, Cee-Lo. The "Forget You" singer said that he has committed himself to too many projects that it's impossible to put all his energy into each of them.
"He always puts 100 percent into his work," a spokesperson for Cee-Lo's management company said in a statement. "With the requirements and time commitment to 'The Voice', on top of heading back into the recording studio and an upcoming book, he feels that he wouldn't give his fans the show that they deserve."
Beside judging "The Voice", Cee-Lo divides his time among his new solo album, Gnarls Barkley's new album and a book. He additionally has a talk show dubbed "Talking to Strangers" which premiered June 22 on Fuse.
Meanwhile, it's still unclear who would be his replacement. Rihanna has two more U.S. dates this month, is due to hit Europe in August and will stay on the road until December this year.
