Reese Witherspoon looked quite patriotic while celebrating Independence Day with her family in Malibu on Thursday, July 4. Joined by her shirtless husband Jim Toth, 42, and son Tennessee, 9 months, the Mud actress, 37, showed off her toned legs in a strapless, navy blue, polka-dot tankini. Rocking a red manicure, the Oscar winner shielded herself from the sun with a white brimmed hat.

Toth wore a Disneyland hat and blue swim trunks, while Tennessee wore a red, white and blue onesie that had the words "American Boy" emblazoned on his chest. Witherspoon's two children with ex-husband Ryan Phillippe, Ava and Deacon, were M.I.A. during the beach outing.

Witherspoon recently joked about how she embarrasses her kids during a chat with Vanity Fair at benefit for the L.A. Dance Project. "We horrify my children by dancing when the bus comes, with different moves," she revealed. "We're like, 'If you don't hurry up, we're going to do the running man in front of the bus.' . . . All of the kids on the bus think it’s hysterical."

Even without an audience full of her children's classmates, Witherspoon can't help but bust a move. "I do a lot of dancing with my kids, and when I get dressed in the morning," she explained. "I have a playlist. A lot of country. A lot of Top 40. My kids love Macklemore, so that."
