After a monthlong hiatus, Nicki Minaj is back on Twitter.

The reason for her disappearance? She wanted to cool things down after a series of rants -- one calling former American Idol judge Steven Tyler a racist for some comments he'd made about her judging on Idol, and another blasting Wal-Mart and Target for pulling Roman Reloaded: The Re-Up off shelves.

But with American Idol retuning to FOX on January 16th, Nicki is ready to play nice with her millions of followers. She writes, "I didn't leave, Barbz -- I was still here in spirit, and you guys know that, so stop with the dramatics."
