Leighton Meester, will forever be Blair Waldorf in our hearts… but she can do a lot more than just accessorize a great outfit. Since Gossip Girl, Meester has married O.C. star Adam Brody, had a baby and made the transition to musician. After her first album Heartstrings and colab with Cobra Starship on “Good Girls Go Bad”, the girl has proved she can sing.

With the holidays right around the corner Meester has graced us with her vocals one more time with her own rendition of Elvis’s “Blue Christmas. Check it out here, you’ll fall in love.
