The boyband, made up of brothers Isaac, Taylor and Zac Hanson, first shot into the limelight with the release of their hit MMMBop.
Now they’re back with a festive album, Finally It’s Christmas, and a tour to go with it.
The brothers made an appearance on Good Morning Britain alongside showbiz correspondent Richard Arnold.
Looking very different to how they did back in the 90s (naturally), Hanson seemed very happy to be back in the spotlight.
“Doing All I Want For Christmas and doing it more of a band sound, rather than the R&B sound.
“It’s a modern classic. It connects with just that right thing, that’s why it’s on our record.”
Zac, Taylor, 34, and Isaac, 37, also wrote some original songs, including the album’s title track.
Then the trio jetted over to the UK for a handful of dates and stopped off at the GMB studios while here.
They played in Manchester over the weekend and Zac said: “We had a great time playing there. It’s great to be back.”
Hanson released another Christmas album in 1997, called Snowed In, as well as a greatest hits compilation this year.
MMMBop did incredibly well upon its release, reaching number one in Australia, Austria, Belbium, Canada, Germany, Ireland, New Zealand, Scotland, Spain, Sweden, Switzerland, the UK and the US.
It didn’t fair so well in Italy where it only reached number six or Finland and France, where it peaked at number four.
Good Morning Britain airs weekdays at 6am on ITV.
