The rapper teased fans with the prospect of new material being released in just a few weeks' time as her gay male persona.
Writing on her official blog, Minaj said: "Roman will be in rare form this time. You know why? Cuz he no longer gives a f**k. (sic)
"He realised that his core matters the most. Everyone else will figure it the f**k out. He can no longer be censored. that's not Lewinsky on a$$. its Roman."
She added: "He has 2 more weeks in boarding school. We're going to pick him up now. When he lands, he will address the nation in the form of music. He will also announce the date."
The cryptic message suggests Minaj will announce new music on the one-year anniversary of her debut album Pink Friday, which was released last November.
The official blog post has since been removed by Minaj or a member of her team.
Minaj has previously revealed that Roman would play a larger part on her future album, saying the material "won't disappoint".
