Miley Cyrus is at it again as she did the move she popularized this year so much – twerking. She was spotted at the Jingle Ball 2013 where she had a Christmas-themed set where dancers were seen everywhere including little people, a bad Santa and a big green Christmas tree costume. In the process, Miley grabbed a boob of one of the dancers and twerked on the bad Santa. See pictures of her daring moves.
