A recent social media post of Britney Spears suggests that she has been sweating really hard in the gym to tone up her abs.
Showing off her washboard stomach and trim figure, the 34-year-old singer shared a pic on her Instagram page and captioned it as, "Long day recording...now it's facial time!" the Mirror reports.
In the pic, the 'Pretty Girls' hit-maker was seen donning a cropped sweater and low-waist pajama pants to flaunt her enviable abs.
Earlier, Spears showed off her svelte figure in low-cut black jumpsuit during her appearance at the Linq hotel-casino in Las Vegas.
