Watch out, Beyonce. Blair Waldorf could tread into your territory.

Besides acting, another love in Leighton Meester’s life is singing. This Texas-born, Florida-raised girl inked a deal with Universal Republic in 2009, and released her first single “Somebody to Love” that October. Leighton also collaborated with Cobra Starship on their hit “Good Girls Go Bad,” which peaked at #7 on the Billboard Hot 100 list.

On the acting front, Leighton moved to Los Angeles at 14 to pursue her ambitions. Since landing the role of Upper East Side’s most fashionable dictator, she’s lit up the big screen in films including, Country Song with Gwyneth Paltrow, The Roommate, and Monte Carlo.

In addition to those on-screen and musical talents, Leighton was also named by People as one of their 100 Most Beautiful in 2008, and #17 on Maxim’s  Hot 100 of 2010 list. Famous designers including Vera Bradley and Missoni took notice and tapped Leighton, who ironically doesn’t enjoy wearing makeup outside of work, to rep their brands.
