First up, Nicki Minaj! Now the girl has rocked the color off and on over the past few years. Even sporting it in a number of music vids & guest appearances! Next, our girl Katy Perry! She got the trend started back in 2010 by first rocking it in her "California Gurls" music video & kept it going for some time after that. She started off with the blue wig and then went all out, actually dying her hair!

And last but not least, Demi Lovato. Just like Nicki and Katy, Demi legit changes her hair color every other month, and we can never keep up! But, her blue 'do has been here for awhile now & we LOVE it!

Which diva do you think rocks blue hair the best!?
