Britney's hitting the yoga studio now that she's back in town following a tropical vacay in the Turks & Caicos with her mom. Brit loves her workouts and on Thursday she did some hot yoga as she was escorted by a hunky new bodyguard!

Britney carried two huge bottles of water to replace all that she sweated out. She had her hands full just with that so her security detail carried her yoga mat and purse.

Spears was clearly in a fun mood yesterday, posting a "One More Time"-throwback on Instagram. Wearing a plaid skirt and a white top tied at the front to show off her impressive abs, Britney captioned the pic explaining that she went "shade shopping" but didn't find anything to buy other than a bracelet. Interesting sense of humor -- but it sent fans off the deep end with his 90s feels. Brit looks the same today as she did in 1998!
