Dianna Agron, Katy Perry and Lauren Conrad were just some of the stars who dyed their hair a crazy color last year, and now it appears that one actress wants to keep the trend going in 2012.

Dakota Fanning was spotted rocking a pink-tinted ponytail while heading to ballet class at a gym in Studio City, Calif. on Thursday.

The 17-year-old actress recently debuted a mature new look on the February cover of Cosmopolitan by wearing a plunging, figure-hugging J. Mendel dress. Fanning was named the magazine's "Fun Fearless Female of the Year," following in the footsteps of Mila Kunis (2011) and Anna Faris (2010).

Fanning, who's in the midst of her freshman year at New York University, told the magazine she's always felt comfortable in her own skin, even in the glare of the spotlight.

"Since I was young, I've always known who I was," she said. "I never really had to go through finding who I am. I've always felt really secure."
