Nicki Minaj is a busy lady: She's a rapper, a singer, an 'American Idol' judge, a makeup maven, a clothing designer and the face of a fragrance. As a result, she doesn't have a ton of time to devote to touring anymore -- but that doesn't mean that she's done promoting 'Pink Friday: Roman Reloaded: The Re-Up.' In fact, she has another single on the way!

Minaj only just released her most recent single, 'High School,' featuring Lil Wayne, but she already has another collabo on deck.

"We might have one more, and I think the Barbz know which one it will be," Minaj told MTV News. "I've been working with Ciara a lot actually. I'm in the studio to finish up a couple things for her today, amongst other things, but she has this dope, dope song. I can't wait for the Barbz to hear it, so we might end up doing the record ['I'm Legit'] I have with her as well."

As far as touring in support of 'The Re-Up,' Minaj admitted it's likely not in the cards -- but that's because she has more music on the way. "I don't think I can. I really would love to, but I don't think I'll have the time, because I'm also going to be launching a few products this year that I'm really going to have to lend myself to," she explained. "The clothing line, I have a drink that's about to come out and these new speakers that you guys are going to see a commercial for this week or next week. So I have a lot of things that the business side of me has to work on, and I also want to be here so I can write. I obviously am going to start working on the third album very, very soon. I'm getting beats as we speak. I just haven't started writing, but that's my biggest priority at this point."

You hear that, Barbz? More Minaj music is coming! Silver lining to every non-arena cloud.
