Britney Spears flashes rock-hard abs in sexy new gym selfies

Britney Spears is still putting in the work (b-tch!) in the gym, and it's showing!

The "Slumber Party" hitmaker took to Instagram on Tuesday to share two sexy selfies of herself from her home gym. The mini Instagram slideshow features one close-up mirror selfie and one from farther away, yet both flaunt her incredible rock-hard abs.

Clad in a sports bra and teeny spandex shorts, the 35-year-old singer was clearly feelin' herself during her latest gym session -- and so are we! The blonde bombshell looks absolutely amazing in her latest social media post, and it may even inspire us to hit the gym, too.

Sharing sultry snaps from the gym is nothing new from Spears, of course. The mother of two sons frequently gives her fans a peek into her gym life as she continues to stay in shape in between her Piece of Me shows in Las Vegas.

See her gym selfies -- and more! --  in the gallery below:
