While warming up for a show, Britney Spears and her niece, Lexie, wished Madonna a happy belated birthday. The Material Girl celebrated turning 58 on August 16.
Spears posted a video of her and Lexie getting in an adorable workout to Madonna's classic "Vogue." Although Spears has used snakes as stage props in the past, the use of a foam roller is certainly a much safer alternative.
This is definitely the best way to spend some time with family and get the blood pumping.
