Britney Spears Instagram PHOTO: 'Piece Of Me' Singer Flaunts ABS In Sexy Underwear For Steamy Photo Shoot!

To show off her comeback, pop singer Britney Spears took to Instagram to share with her followers a stunning snapshot of herself. Posing in her sexy underwear, the 'Piece of Me' songstress heats up in her latest photo-shoot.

If you check out the music star's Instagram account, you will definitely notice the blonde recording artist displaying her tight abs and flat tummy. Wearing enticing black panties, we see the '90s pop icon stretching out her taunt tummy in a pink-sleeved crop top.

Spears writes beside the pic, "Amazing amazing shoot with Jeff Lipsky today! Been working hard this summer! So ready to bring it for the next round of #PieceOfMe shows next week."

According to his website, Lipsky has shot with a variety of clients, from Vogue to Outside magazine. In his photography reel, Chris Pratt (Guardians of the Galaxy), talk show shot Chelsea Handler, and Eva Mendes show up in his gorgeous snapshots.

This is all part of a recent publicity push to support Spears' latest album and Piece of Me concert tour, which began in 2013. Due to high demand for the popular singer, a slew of new show dates have also been added.

Remember when the starlet shaved off her head and bashed a car with an umbrella. Or can you recall the time she cried in front of Matt Lauer? Times have changed for the better. This fabulous photo almost makes you forget her drama-filled decade.

Back in shape and confident about her body, Britney Spears flaunts her sexy physique in a teasing photo shoot. Readers, what do you think of the Instagram photo?
