Looks like someone has lightened her locks for summer!

After being a brunette for over a year, Ashley Tisdale was spotted leaving the Byron and Tracey Salon in Beverly Hills on Sunday as a freshly dyed blonde.

"It's summer and I'm ready for some FUN!" the Hellcats star tweeted on Monday, along with a TwitPic  showing off her new hue.

When the 26-year-old actress dyed her hair brown in March 2010, she admitted to Us Weekly that she still favors a set of sunny strands. "My natural hair is dark, but I like being blonde -- blonde is more fun!"

In addition to being lighter, brighter, and happier, the star says that there's another thing she's noticed in her experiences as both a blonde and a brunette: "You get different guys according to your hair color," she told Us, even though the natural brunette is smitten with her music video director beau Scott Speer.

Tell Us: Do you like Ashley as a blonde or a brunette?
