For the first time in 'America's Got Talent' history, celebrity guest judges will join the panel as part of the all-new Judges' Callbacks round, marking one of the biggest format changes the series has ever introduced.

Following the 'Live Acts Revealed' special on Tuesday, July 28, each judge will personally select a group of standout acts for one more performance, where they will compete for the remaining coveted spots in the live shows. This two-week event will air on Tuesdays, Aug. 4 and 11 at 8 p.m. ET/PT on NBC, before the live shows kick off on Aug. 18.

Star-studded guest judges include Spice Girls icon Emma Bunton reuniting with Mel B, Golden Globe and Emmy-nominated comedian Nikki Glaser joining Howie Mandel, social media sensation Lele Pons and Latin Grammy-winning superstar Sebastián Yatra teaming up with Sofía Vergara, and global pop star Normani alongside Grammy Award-winning songwriter and producer Poo Bear joining Simon Cowell.

The returning 23 acts will feature an exciting mix of talent including powerhouse singers, dynamic dance groups, standout comedians and unforgettable variety acts full of unexpected surprises. Alongside their celebrity guest judge, each judge will work closely with their chosen acts, offering invaluable feedback and guidance as they prepare for one additional performance and their last opportunity to earn a spot in the live shows.
