Dianna Agron fills us with ‘Glee’ [SLIDESHOW]

In Hollywood, it’s hard to make a successful style change. Everyone’s watching, and scrutiny is inevitable. But “Glee” star Dianna Agron, who recently shortened her long blond locks for a more sophisticated look, pulled off the switch beautifully. That’s not the only change she’s seen in 2011, either. In February, the 25-year old allegedly broke up with actor Alex Pettyfer, who reportedly terrified, threatened and harassed her after the split. This hasn’t been the easiest year for Agron, but hopefully she’ll have a better experience when she goes on tour with fellow “Glee” castmates this summer. In honor of her risk-taking abilities and upcoming D.C. visit, we present our favorite photographs of Dianna Agron.
