Ashley Tisdale can't stop smiling, and it may have something to do with her new blonde 'do!

Even though she's got it covered up here with a ball cap and hoodie, the Disney star has been spotted flaunting her new hair all over LA, and looking fab while doing it.

We caught up with Tisdale as she exited Planet Blue in Beverly Hills, after stocking up on a few essentials before she leaves for Las Vegas this weekend.

Ash is hosting a birthday bash at PURE Nightclub on Friday, and then a pool party at the Venus Pool Club on Sunday.

Blondes really do have more fun!!
