You might be able to guess today's celebrity cleavage if you're a fan of television shows and teen romantic comedies.

These perky pups belong to an actress who's made a name for herself by starring on a popular show on The WB/CW network that ran from 2003 to 2012.

She also helped Brittany Snow, Arielle Kebbel and Ashanti try to destroy the reputation of the hottest guy in school in a romantic comedy that hit theaters in 2006. Here's a hint: she played the slutty hippie girl.

These days, she plays a detective on an NBC drama, so you might have seen her pretty face again. Can you guess who it is?
