The three brothers were known for their hit MMMBop back in 1997, but they are now back with brand new music.
Isaac, Taylor, and Zac were so young when they first started out in the music industry so viewers were shocked at how they now looked.

What’s more astounding is that they now have 12 children between them and have transformed into lovely, dashing men.
Lead singer Taylor, 34, has five children with his wife Natalie; sons Jordan, 14, River, 10, and Viggo, eight, and daughters Penelope, 12, and Wilhelmina, four.
Zac, 31, has four children; John, nine, and Junia, six. The eldest member of the band, Isaac, 36, has three children; Clarke, 10, James, eight, and three-year-old Nina.
Hosts Eamonn Holmes and Charlotte Hawkins couldn’t wait to ask them about their new music.
Eamonn also joked that they couldn’t have just made a living from the one song.
They said: “God no! You get up every day and go to work, whether it’s on stage, in the studio… we do a lot of things. It’s a passion.”

Their new single I Was Born also features their children.
Talking to People magazine about the decision, they said: “Featuring our own kids made sense because we knew they would share an honest performance.
“We loved the fact that it added another dimension to the story of pursuing our dreams for the last 25 years.”
