Two days after Rihanna publicized her "Last Girl On Earth Tour," Nicki Minaj, who was announced as an opening act alongside Ke$ha, has pulled out of the trek.

"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," Lil Wayne's protégé tweeted today (April 7). About 19 hours before that message, Nicki posted another tweet that seemed to allude to the forthcoming announcement, stating, "*sighs* do i say this...hope the barbz will understand...hate letting them down. *sighs again while in deep thought*"

No reports yet on whether or not there will be a replacement for the rapper on the 25-date tour.
