Britney Spears and her son Jayden James Ferderline are gonna work it on out!

The Circus singer and her four-year-old put in some time at a kiddie gym in Los Angeles on Thursday, getting some exercise and looking extremely cute while doing so. While Jayden opted for a Batman T-shirt accessorized with a fake tattoo on his neck, Brit-Brit went with a black backless number that brought a little glamour to the workout.
