LOS ANGELES, July 2 (UPI) -- When Britney Spears' mom hears her daughter's song "Toxic" on the radio, she dances of course.
Jamie Lynn Spears was riding in the car with her mom, Lynne, on Thursday when she recorded her rocking out to her older sister's mega hit. Mama Spears can be seen throwing her hands in the air and dancing around while Britney's song can be heard playing in the background.
