Britney Spears shows off toned tummy in sexy 'sweats and a t-shirt' Instagram

Britney Spears showed off her toned tummy on Instagram over the weekend!

In fact, not only did Spears flaunt her incredibly fit physique, but she also give a little peek at her intimately-placed tattoos -- including one of a cross -- below her waistline.

"What's better than sweats and a tshirt?" she captioned the shot along with a smiley face emoji.

The mother-of-two is also wearing two red sweatbands on either one of her wrists, a black charm-adorned choker and hair extensions in the photo.

Of course, this isn't the first time Spears has dropped jaws with one of her Instagram photos. The star has been sharing more and more sexy pics of herself online as she continues to get in tip-top shape. Among some of her notable posts have been videos of her putting in work in the gym, including one last week of her wearing a crocheted bikini top while exercising.

The post came over the same weekend that reports emerged she would be ending her hugely successful Las Vegas residency, "Piece of Me," in December. The singer will also be touring throughout Europe and Asia over the summer, including a show in Israel that the country pushed back an election to accommodate.
