The pop brothers were promoting their newest song Child At Heart on the ITV breakfast show This Morning, a far cry from their 1997 hit MMMBop.
When discussing how popular their MMMBop single was, the band agreed that the success was due to the fact they wrote it themselves.
“When you’re writing your own music, you’re thinking about like ‘What will my music be? What will people be getting from that?’,” the group explained.
It didn’t take long for fans to chime in about what they were seeing, flooding social media with comments.
“Since when did the oldest one from Hanson get so good-looking? I remember three geeky lads with long hair,” one wrote.
“Ahhh I loved Hanson back in the day, I feel really old now,” another one added.
“Still hot, aged well boys,” said a fan.
“Hanson as men. I’m not sure how I feel about that,” a fourth said.
There were also plenty of people who savaged their appearance, commenting that they don’t look like pop stars anymore.
“Hanson now look like accountants,” one observed, while another criticised their performance, “MMMBop doesn’t really sound right when grown men are singing it.”
The trio have been busy since their debut, releasing six albums and becoming parents — with 15 children between them.
The oldest band member Isaac, 41, has three children, while lead singer Taylor, 39, has a whopping seven, and youngest member Zac, 36 has five.
Hanson is embarking on a tour to support their latest album Red Green Blue, and are planning to visit Australia in November this year.
