The whole world fell in love with Britney Spears when she dressed up as a naughty school girl for her 1999 video Hit Me Baby One More Time. And while it seemed like she could do no wrong, she eventually hit a bit of a “rough patch” and took some much-needed time away from the limelight..

Thankfully, she got her life back on track, and the 34-year old pop superstar is doing better than ever, with a super-successful residency in Las Vegas. Sure, Britney still likes to indulge her sweet tooth from time to time, but as you can see in this Instagram workout video of hers, she’s willing to put in the work afterwards.

After Cheesecake Factory you do this… Treadmill and weights ?
