The actress has just landed a role in the upcoming Dora the Explorer live-action film, alongside Eva Longoria!
Pia will play Dora's aunty, who is the mother of Dora's sidekick, Diego. Dora's mum will be played by Eva, making the pair sisters on the screen!
"[I] can confirm Pia Miller as Diego's mother in the film. Diego was played by Jeffrey Wahlberg," a production spokesman said. Yep, Jeffrey IS related to Mark Wahlberg... he's his nephew.
Last week Pia attended Sydney's GQ Men of the Year Awards, where she managed to stay pretty quiet about her new role.
"I have been shooting in Queensland on a feature film," Miller told the Herald Sun, adding that she loves acting on both the big and small screens. "The creative process, whether it comes in the medium of film or TV, I don't mind which one I do."
