Is 'Glee' prepping a Nicki Minaj number? We think so! Dianna Agron, who plays Quinn, was spotted grabbing coffee last week with a head full of hot pink hair. It has since been revealed, by the starlet herself, that her very girly 'do is for work ... And we can only assume that means 'Glee'!

"Hey all! The pink is for work. Tried to keep it a, that is all I will say! Thanks for all the nice comments on it! #barbiepink," Agron tweeted Friday. Since 'Glee' is notorious for its Top 40 covers and original mash-ups, our eyes immediately jumped to the actress' strange hashtag, which lends us to think of a certain Barbie-friendly hip-hopper.

Will 'Glee' turn things up in Season 3 with Minaj's 'Super Bass'? We can only speculate, but being that she's so hot in 2011, and fabulously pink, we think it's entirely possible that a Nicki Minaj rendition is Agron's not-so-sneaky little secret -- for now, anyway!

Season 3 of 'Glee' kicks off on Sept. 20.
