He revealed that the next 10 acts performing this week were from all over the world and that it would be difficult to choose one.

Great job @isyourmindsafe!🏾 #AGTAllStars151He’s back to read our minds! Great job @isyourmindsafe!👏🏾 #AGTAllStarshttps://t.co/3xPOGG8BtrMentalist Peter Antoniou took to the stage to impress the judges and audience. He previously appeared on AGT season 16 and blew everyone's minds with his psychic reading. While talking to the judges back then, he revealed that when Sofia Vergara's now-husband Joe Manganiello proposed to her, a rainbow appeared, one that the judge claimed no one ever knew.Peter reached the semi-finals, but he was eliminated soon after due to the lack of votes and because he stumbled while reading Sophia's mind. He eventually received the X buzzer from Simon because of the mistake. Ahead of his audition for AGT: All-Stars, the mentalist revealed that after his previous stint, he got a chance to perform live in Vegas and wanted to prove his mettle once again. View this post on Instagram Instagram PostIn a confessional, the AGT: All-Stars contestant said:"Since being on the show, my life's completely changed. I'm going to theaters, people are coming out.. And it's been such an incredible journey. I think this is my opportunity to really prove that I deserve to be counted amongst all of the All-Stars."Peter realized that Simon was going to be a "curveball," but the mentalist was going to do everything he could to impress the judge. For his audition for the reality talent competition, he called host Terry Crews, audience member Grace, and judge Howie Mandel on the stage for a tea party.The mentalist then began his psychic readings on AGT: All-Stars as he correctly guessed Howie's question about when his son was going to get married, Grace's answer about her future child's name, and Terry's shoe size. However, ahead of reading the host's mind, Simon once again pressed the X buzzer.Peter Antoniou@isyourmindsafeALWAYS happy to have a tea party with @terrycrews and @howiemandel #AGTAllStars #agt @agt @AGTAuditions115ALWAYS happy to have a tea party with @terrycrews and @howiemandel #AGTAllStars #agt @agt @AGTAuditionsThe other judges, Howie and Heidi, disagreed with Simon as they felt Peter had a great talent. Simon, however, maintained that it wasn't about the result but about the process of getting to the result, which was boring and underwhelming. While the judges felt that the superfans could vote for him, the mentalist called Simon impatient.Fans react to Peter Antoniou's audition on AGT: All-StarsFans were left with mixed reactions following Peter's performance.
