Christina Aguilera appears to be hard at work on new music, based on a photo the pop star posted over the weekend. Could the follow-up to 2012's Lotus be around the corner?

Last week, Aguilera covered John Lennon's "Mother" at an exclusive Los Angeles party. And not so long ago, we compiled our 15 favorite Christina performances for her birthday last month.
