Snapshot: Britney Spears previews upcoming sexy magazine shoot...

Looking like hot tamale, Britney Spears shares a behind the scenes snap from her upcoming magazine shoot, which was shot by Jeff Lipsky! 

Some say it's for 'Self' magazine, while others claim it's for 'Women's Health'. I think it's for the latter because Shakira has a similar cover. Her stomach looks great and she's clearly been keeping herself fit for the continuation of her Vegas shows next week!
