The 38-year-old singer star shared on Instagram three photos of herself working out with her trainer, Anna Kaiser, founder & CEO of AKT InMotion.
The mother of two appeared skinnier than ever and super toned, wearing a black cropped tee that shows off her toned abs, paired with black leggings and purple and blue sneakers. She kept her long, curly blond hair loose.
"Dancing and working with @theannakaiser today!!," she wrote.
The singer showed a trim post-baby figure while walking in Barcelona in March and in other pics posted on her Instagram page.
