Jamie Lynn, 24, was casually clad in a black blouse and black and white shorts, as her six-year-old watched on from a chair.

The former Nickelodeon star is set to perform at the CMA Fest in Nashville on Saturday. Meawhile, Britney was looking cool and sassy thanks to a brand new haircut that flattered her features and provided relief from the heat as she enjoyed some retail therapy in Thousand Oaks, California on Wednesday.
