Not everyone is having a merry Christmas and for those who need someone to sing their blues, look no further than Miley Cyrus .<br />The singer released a holiday-inspired song Friday titled, "My Sad Christmas Song."<br />Cyrus, 23, posted a photo of herself, dressed in an elf costume, looking sad while sitting on Santa Claus ' lap.<br />In the ballad , Cyrus croons, "This is my sad Christmas song/I've had it stuck in my head all day long/I wrote it in the car on my ride home/Because I knew I'd walk in the door and I'd be alone."<br />Cyrus then questions why she put up a Christmas tree and even admits that her sister called her a grinch.
