Selena Gomez is changing up her look for 2012, beginning with new blue and purple extensions. The singer tweeted a photo of her new 'do on Wednesday for all of her fans to see.

"Change is good," she wrote with the pic. "My girls @ninezeroone take care of me always :) LOVE." The singer also tweeted a second photo of her vibrant new look.

This isn't the first time Sel has experimented with bright hair. The 19-year-old rocked pink extensions for her 'Hit the Lights' music video shoot in September, and also tweeted a photo of her colorful locks from the set.

Although she's taking a break from music, plenty of pop stars like Selena have been sporting a rainbow of hair colors lately, including Katy Perry, Nicki Minaj and Rihanna.

What do you think of Sel's latest hairdo? Are you into the blue-and-purple locks or do you prefer her as a natural brunette? Let us know your thoughts in the comments.
