and Carrie Underwoodare two of our favorite people, but we have to agree with Kelly on this one!

The 34-year-old "Piece by Piece" singer says that people regularly confuse her with the fellow American Idol winner, but she has no idea why.

"This is my favorite thing. People come up to me all the time," she said on Z100's Elvis Duran and The Morning Show on Wednesday. "OK, we look nothing alike, we sound nothing alike, there's nothing about us that's similar, really, except we were both on Idol.

"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,'" she continued with a laugh. "It always happens! Then a girl that worked with her years ago said the same things happened to her. I think it’s because we're both blonde and from American Idol."

Kelly couldn't help but gush that Carrie is "awesome," but revealed that she didn't actually vote for the country cutie during her time on Idol.

"I have actually voted one time out of all the 15 years of American Idol," she said. "It was for La'Porsha [Renee, season 15 runner-up] and she did not win, and I was so sad! They were both great at the end but I just really, really loved her voice. It was so innate, just so natural."

Kelly was visiting New York City to promote her work on The Hamilton Mixtape, for which she put a new, pop spin on the song "It's Quite Uptown."

"I had never seen the musical and I was super pregnant," she told Duran, referring to her second pregnancy with son Remington Alexander. "I couldn't fly, I was literally weeks away from having my little boy. So they send me this song that's about a little boy dying, in my brain, because I'd never seen the musical! So I didn't know it was a teenage son, I didn't know the situation, anything. I'm just bawling and sending every expletive to [Atlantic Records'] Craig Kallman, going 'Why would you send this to me? This is horrible!' ... But it was so beautiful, it was very hard to record because I recorded it with my little boy."

Kelly welcomed baby Remy in April 2016 and recently told ET that her family is now officially complete.

"We are not having any more kids," she exclaimed. "I mean, there's no time for more kids, yeah. Just, like, fitting everything in is hard enough, and I hate pregnancy. Like, with a capital H."

And she wasn't kidding! "I was mid-pregnancy with Remy and I made my husband go [get] snipped," Kelly revealed. "He didn't -- I didn't have to force him. He was running to the doctor. We both were like, 'Nope!'"
