Lady Gaga performs 'White Christmas' at Jingle Ball 2011

At this years Jingle Ball concert, headliner (and Mother Monster) decided to sing her own rendition of the classic Christmas song 'White Christmas' by Bing Crosby (which, according to the Guiness Book of World Records, is the best selling single of all time).

During the performance, Mother Monster took a little time to share something magical about Christmas:

“I wanted to tell you one very important thing that you will always remember, and remember I was the one that told you the truth about Christmas. To all of you that are listening, Santa Claus, he is real,” said Gaga.
