Rihanna announced via Twitter that rapper J. Cole, who was already on the road with the singer, will fill Green's shoes as her main warm-up act on the tour, which began this month. "#GOODNEWS @JColeNC is our new official opener!" she wrote on Tuesday night. "@CeeLoGreen will no longer be a part of #LOUDtour due 2 commitment with 'The Voice' #Cantmissit."
Jay-Z protégé Cole, who is releasing his debut album, Cole World: The Sideline Story, on September 27, just wrapped up the video for first single "Work Out" with director Jake Davis on Tuesday.
Green had to leave when his schedule became too crammed with other commitments, including his judging gig on the hit NBC talent competition "The Voice," which is also presenting a tour this summer.
"He always puts 100 percent into his work and 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," Green's spokesperson said, according to The New York Times.
Rihanna's Loud tour travels the U.S. through July 24 before heading to Europe in August. It's set to wrap up in late December.
There was a similar switch-up for Rihanna's Last Girl on Earth Tour in 2010, when Nicki Minaj pulled out at the last minute and was quickly replaced with Travie McCoy. Ke$ha also opened on that tour.
