Mariah Carey, U2, and... Leighton Meester?

If you think that's a list of the most influential artists of the decade, well... I feel a bit sorry for you.

BUT! If you caught on that these are the pop stars who have taken on the classic tune, "Christmas (Baby Please Come Home)" then you are one smart Christmas cookie.

Check out Gossip Girl star Leighton Meester's latest release from her recent dive into the music biz. The song is available on iTunes and as part of A Very Special Christmas Volume 7, a compilation also featuring Miley Cyrus ("Rockin' Around The Christmas Tree"), Colbie Caillat ("Have Yourself A Merry Little Christmas"), Kellie Pickler ("Santa Baby") and Kristinia DeBarge ("Do You Hear What I Hear?").


And now, the true test: how does it compare to Mariah's version?
