The youngster from South Wales wowed the panel at the weekend as she performed Whitney Houston's I Have Nothing.
Amanda Holden described the performance as "mind blowing" while David Walliams said Maia was the reason that kids are allowed to audition for the show, claiming she outdid many of the adult wannabes.
Although in some cases, that's not exactly too difficult.
Speaking to the South Wales Evening Post, Maia revealed how her family have inspired her to perform, explaining: "I've always loved singing.
"I've been brought up in quite a musical family, my mother likes singing and other members of my family like playing various instruments and stuff like that."
Maia says she only auditioned for the show for the "experience" but with four huge yeses she's through to the next round and could make the semi-finals, singing live to 10 million viewers at the end of this month.
"I thought the comments were all really nice and I can't wait for the next step," Maia said. "It would be amazing if I could get to a position where I could perform before crowds like that more often."
Other acts who got through at the weekend included princess pop group Misstasia and dance crew (of sorts) Old Men Grooving.
