(NBC News) Tonight is the second of four “judge cuts” episodes for “America’s Got Talent” leading to the start of the live shows on August 14th. Olivia Munn joins the AGT judge panel Monday night as a guest judge. Munn is especially excited about the chance to hit the golden buzzer, sending someone straight to the live shows. “That is so much pressure. Because you don’t know who comes afterwards, because you think that was a great one, but this one was even better,” Munn says. Accordion player Hans is among the 18 acts Munn will see Monday night, as well as a magician with amazing sleight of hand. “I’m just so excited and nervous about doing the wrong thing. I’d like to see them all then they come back, and then I pick the golden buzzer,” Munn says.
