A well-known popstar from the 2000s looked completely transformed as she appeared on The One Show this week.

Fans were left stunned when she appeared on their screens, sporting a bold new look that was a far cry from her early days in the industry. Viewers took to X to express their shock at her striking appearance, with some even saying they still believed she was “25 years old.”

The Scottish singer, 49, showcased an edgy undercut hairstyle, complemented by pink lipstick that matched both her jumper and nails. Best known for her hit single Suddenly I See and her 2004 album Eye to the Telescope, the 49-year-old singer left audiences in disbelief with her dramatically different appearance as she chatted with host Alex Jones.

Comments flooded Instagram, with one fan writing, “What? Thought she was still like 25,” while another praised her, saying, “That whole album was amazing and she’s looking very cool.” KT’s appearance on the show was to mark the 20th anniversary of her song Suddenly I See.

Reflecting on the track’s legacy, she shared: “I have people coming up to me going, ‘I’ve listened to you my whole life. “I’m like, ‘what?’ It was amazing because the song ended up much better known than me. I remember going to a party and someone went, ‘Oh, what do you do? I said it was the song at the beginning of The Devil Wears Prada, and she went, ‘Oh my God, you’re on the party playlist.’ I was so lucky to have a song that connected with people like that.”

In January, KT opened up about the possibility of adoption, revealing it’s something she has thought about, especially since she was adopted herself as a baby. The singer, who does not have children, was just a few days old when she was placed for adoption and later taken in by Scottish couple David and Rosemarie Tunstall.

As she nears her 50th birthday, the idea of adopting a child is on her mind. Now living in the U.S. with her partner Chris Light, she spoke to Saga magazine about her experience with adoption. “I was adopted along with my older brother, but my mum and dad did have a son after being told they couldn’t have children. Mum always joked, ‘Everyone else got what they got, but you got chosen,’ though the truth is you’re always going to have a bit of an abandonment issue.

“It didn’t hit me until late in life. I found my biological mother at the age of 23 and it was really enriching to my life—but tough. I had never been able to find my biological father, so I went on ITV’s Long Lost Family, and they did. But he’d passed away.

“When the programme reached out to my two sisters, they had no idea they had another sibling. They broke it to them gently, saying, ‘We think you’ve got a sister you didn’t know you had—and she’s famous’. And the younger one said, ‘It’s KT Tunstall!’ She grabbed my album, which they had in the house, held it up against a picture of our dad, and just went, ‘They look exactly the same.’”

Born to biological parents Carol Orr and John Corrigan, Tunstall was placed for adoption just 18 days after birth.
