Britney Spears took to Instagram on Monday to show off her hot bod in a new selfie. While posing in the mirror wearing a crop top sweater and flannel PJs, with her hair styled in a messy bun, the pop star showed off her tight tummy.
"Long day recording...now it's facial time!" she posted with the cute candid.
The "Perfume" singer's Las Vegas residency sure has been doing wonders for her bod -- this might be the best shape we've ever seen Brit Brit in!
Spears has had a pretty great month, too. The mother-of-two celebrated her 34st birthday on Dec. 02, with her family and shared a few fun photos from the festivities.
