Kelly Clarkson gets mistaken for Carrie Underwood

Kelly Clarkson gets mistaken for Carrie Underwood.

The 'Because of You' hitmaker says she is constantly confused for the 'Before He Cheats' singer because they are "both blonde and from American Idol" but sees it as a great compliment.

Speaking on Z100's Elvis Duran and The Morning Show on Wednesday (07.12.16), Kelly said: "This is my favourite thing. People come up to me all the time. 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.' 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."

Meanwhile, the 34-year-old singer - who has River Rose, two, and seven-month-old Remington Alexander with her husband Brandon Blackstock - previously admitted she thinks about giving up her singing career "all the time".

She said: "I was in a very dark place for a long time. It's just so hard to have normalcy. I love to sing, and I love to talk to people at meet and greets.

"It's just all the c**p that comes along with this job ... I don't love traveling, because I'm never home. It's hard when you have a family."

Asked if she has thought about giving it all up, she added: "Oh, all the time. I mean, I'm always going to be a singer, but the level I'm at ... I have constant guilt. I don't have to work; I think it's because I have that option that I feel the guilt. But it's important for my girls, especially, to see me as a woman accomplishing all these things while nailing it as a mom. I always come back to that."
