Nicki Minaj posted a pair of revealing pictures on her Instagram, along with some cryptic captions. While fans have been clamoring for some new music, Nicki looks to the past, quoting what many consider to be her finest hour - the "Monster" verse. It's not clear what prompted the "Monster" throwback, though the pictures do feature both a pink wig and a thick ass. Still, Nicki concludes the caption with two hashtags, #IssaNotherSecret and #PinkInches. 

"Who's ready?" asks Minaj, and while we're not sure what we're getting ready for, it's safe to say that something is coming. Check out the photoshoot, which finds the rapper dressed down in what looks like a padded room.
