The star took to Instagram over the weekend to share an adorable photo of her and her boys chowing down on a plate of fries at the Cheesecake Factory, and then later shared a video of her working off the greasy treat. In the first snap, the "Make Me" singer poses next to her sons Sean, 10, and Jayden, 9, as they enjoy a delicious meal together. The trio looks happier than ever as they smile for the camera—Spears simply captioned the 'gram with a fork and knife emoji. Later that day, the singer showed us how she's able to indulge and still stay in tip-top shape, and it involves a rigorous workout regime. "After Cheesecake Factory you do this... Treadmill and weights," Spears wrote alongside a video of herself exercising in a bikini top and cropped leggings. And it looks like her dedication is really paying off. The mother of two shared several snaps of her and her sons enjoying some fun in the sun at Six Flags Hurricane Harbor in Los Angeles last week, where she showed off her fit physique in a bright orange two-piece swimsuit.
