Judd Apatow hit up the Sundance Film Festival in Park City, UT, on Thursday night with one very cool girl on his arm: his daughter Maude Apatow. The 17-year-old actress did her dad a solid by inviting him as her date to the red carpet premiere of her new movie Other People, wearing a pretty floral dress and some black Tory Burch booties [1]. For anyone who'd last seen Maude playing the role of young Sadie [2] in her dad's movies Knocked Up and This Is 40, she sure does look grown up, right? She's even come a long way since appearing in season four of Girls. Keep reading to see more photos of their father-daughter date, then check out the Apatow family's cutest pictures [3]!
