Four years later, the now 16-year-old is broadening her reach with a lead role in Disney's Stargirl, a film adaptation of the YA novel by Jerry Spinelli. The basic storyline: A coming of age love story between a shy teenage boy and a quirky, misunderstood girl, played by VanderWaal. With the movie dropping on Disney+ tomorrow, March 13th, Hollywood is buzzing about the up-and-comer - and for good reason. Talent aside, she's as charmingly eccentric as her new on-screen persona, which is often seen in her nail polish, hair accessories, and more.
