Entertainment Music Kelly Clarkson Once Signed an Autograph as Carrie Underwood After Being Mistaken for Country Star Kelly Clarkson and Carrie Underwood were both winners on the early seasons of American Idol By Ally Mauch Published on October 17, 2020 11:30 AM Share Tweet Pin Email American Idol doppelgangers? During Friday’s episode of The Kelly Clarkson Show, Kelly Clarkson recalled a time when she was mistaken for fellow singer and Idol winner Carrie Underwood, despite saying they “look nothing” alike. The host, 38, sat down with guests Michelle Buteau and Cheryl Hines for a segment called “I'm Awesome At Being Awkward,” in which they had to say what they would do in various awkward situations. One of those situations was being mistaken for another person, and Clarkson had the perfect story to share. "This girl came up to me and was like, 'Oh my god, your song 'So Small' is one of my favorites,'" Clarkson said. "And I kept thinking, 'I don't have a song "So Small." ' And then she said another song and I was like, 'Oh, you think I'm Carrie Underwood.' " Matt Baron/Shutterstock.

"I was so embarrassed for her that I just…She was like, 'Can you sign this?' And I totally signed 'Carrie Underwood.' I think that might be illegal!" This isn’t the first time Clarkson has opened up about fans thinking she was Underwood. “People come up to me all the time. Okay, we look nothing alike, we sound nothing alike, there’s nothing about us that’s similar, really, except we were both on Idol,” she said on Z100's Elvis Duran and The Morning Show in 2016. “People are always like, ‘I love your song, "So Small,” and I’m like, ‘Thank you. Thank you, I think you’re thinking I’m Carrie Underwood.’ It always happens!” RELATED VIDEO: Kelly Clarkson Feels 'More Connected' to The Voice Artists but Misses Energy From the Audience Kelly Clarkson Pokes Fun at Tabloid Rumors of a Feud Between Herself and Carrie Underwood The pair have been friends since American Idol brought them together.
