Uma Thurman helped her kids get a jump on their summer vacation with a visit to Six Flags Great Adventure in Jackson, N.J.
The pregnant actress chaperoned daughter Maya and son Levon – plus some of their friends – at the theme park, where the kids rode the rides – specifically the SkyScreamer and Batman the Ride. Thurman, meanwhile, sat out the roller coasters but told her guide she was excited to return next year after she gives birth.
The actress and her family also dined at Best of the West, where they snacked on sweet treats such as cotton candy and ice cream, as well as water ice. And she took time to pose for pictures with Looney Tunes characters Sylvester and Wile E. Coyote before heading out of the park.
