And then there were two. Only a couple days after announcing her slot on Rihanna’s “Last Girl on Earth” tour featuring Ke$ha, Nicki Minaj has pulled out so she can finish recording her album.

Lil Wayne’s protégée will no longer be joining the “Rude Boy” singer on the road. She revealed the news on Twitter, writing, “Barbz I’m sorry 2 say I will not be going out on RiRi’s tour. I’ve decided 2 use that time 4 the completion of my album. Hope u understand.”

A rep for the rapper confirmed the report to staging-rapup.kinsta.cloud, saying, “She has to get her album completed, so the timing wasn’t right.”

Rihanna’s tour will continue without her. The trek kicks off in Seattle on July 2, making 25 stops at arenas across the U.S. and Canada, including the Staples Center and Madison Square Garden.

Nicki Minaj is prepping her Young Money debut with producers Swizz Beatz and Sean Garrett, among others. A video for the first single, “Massive Attack,” was released last week.

UPDATE: Nicki responded to disappointed fans and thanked Rihanna in a new tweet. “Barbz, Thx 4 understanding. And Thanks to Rihanna 4 being a sweetheart and extending this great opportunity 2 me. Support the show! Luv, HB,” she wrote.
