Happy Birthday 'Pretty Little Liars' Star Tammin Sursok!

Tammin SursokPut on your flashiest sunglasses and wish "Pretty Little Liars" actress Tammin Sursok a happy birthday today! The Aussie beauty is 27, and we hope she's celebrating in style — like, say, shopping for some new shades.

Since "PLL" doesn't start shooting again until September, Tammin's eyes are probably feeling a little sensitive toward the sun. She constantly sports the finest in blindness-concealing eyewear as her "PLL" alter-ego, Jenna, so we hope she's taking the proper precautions in protecting her peepers from UV rays.

Sunglasses aside — hopefully Tammin isn't thinking too much about work on her special day — we suggest celebrating the anniversary of the birth of one of our favorite new actresses by marathoning all ten episodes of "Pretty Little Liars." But maybe that's just us.

If you've already watched the entire season, you can get another Tammin fix before "PLL" comes back early next year. She's currently appearing on the final season of "Hannah Montana" (which, for some reason, is now called "Hannah Montana Forever") as Siena, the love interest of Hannah/Miley's crazy brother, Jackson.

Up next for Tammin: the big screen. She's currently working on "Sleepaway Camp Reunion" with Alexis Bledel, David Henrie and Drake Bell, and the horror comedy film "Husk."
