Katy Perry is curious to know more about the 19-year-old from Springville, Utah, and asks her about her social media following, which is when we find out how modest Abby is. Apparently, she just joined Instagram on Nov. 24, 2020. “I didn’t want to come off as showing off,” Abby tells Katy. To which Lionel Richie says, “We are in the show off business,” a musical cue if there ever was one, and all three judges break out singing, “There’s no business like show business like no business I know.” And Abby shows off just a little bit, singing and playing piano to “All I Want” by Kodaline.
