Happy birthday to the always gorgeous Leighton Meester! The actress, who is perhaps best known for her role playing Blair Waldorf on Gossip Girl, turns 30 today. Congrats, Leighton!

Since first emerging on the acting scene, Meester's seen major success as both an actress and a musician. In 2010, Meester landed a part in the country drama film Country Strong. From there, she starred in several films, including The Roommate (2011), Monte Carlo (2011), The Oranges (2011), and the comedy-drama The Judge (2014). Then, in 2014, she went on to make her Broadway debut in Of Mice and Men.

In addition to acting, the multi-talented star's been trying her hand at music for several years now. Back in 2009, Meester released her first single "Somebody to Love," featuring Robin Thicke. Her second single, "Your Love Is a Drug," came out in 2011 and her debut album, Heartstrings, dropped in 2014.

On top of her nonstop career, Meester and actor hubby, Adam Brody, became parents back in August, 2015, when they welcomed a little girl, Arlo Day Brody. Despite juggling multiple projects and being a working mom, Meester always arrives looking fresh-faced and put-together in the public eye. To see for yourself, we've rounded up Meester's amazing transformation through the years.
