The 'MMMBop' hitmakers - comprised of brothers Isaac, 36, Taylor, 34, and Zac, 31 - couldn't let more than two decades as a band go by without something kind of celebration and just for their fans they've decided to hit the road for the special milestone.

They will kick off 'The Middle of Everywhere 25th Anniversary Tour' in May at Hop Jam Beer and Music Festival in Tulsa, Oklahoma.

Taylor said: "Making music together for 25 years is a milestone that we had to acknowledge, and what a better way to do it than with an anniversary tour.

"This year is not only about the two decades of music, it's about celebrating the incredible community of fans who have been with us, singing along year after year."

The tour announcement comes after they revealed in December that they'd "just finished" working on a new festive LP following their success 20 years ago with 'Snowed In', which is slated for release in 2017.

The trio revealed tracks including 'Winter Wonderland' and 'Blue Christmas' will feature on their compilation.

They announced the news via social media, which saw them post links to their 1997 album, including never before seen footage of when they joined forces to record the popular record.

The group shared a string of tweets, which read: "20 years ago we made Snowed In. Just finished a new Christmas album for 2017 -Z https://youtu.be/ueRMiD-busY via @YouTube

"HANSON's New Christmas Album: Ooh Christmas -Z https://youtu.be/1ZvBr3bJZgQ via @YouTube

"Live version of Winter Wonderland, studio version will be on the new Christmas album in 2017 -Z https://youtu.be/86kfYFNDtNA via @YouTube

"Just posted a new Christmas Song on http://Hanson.net part of the members Super Digital Pants album -Z #Merry #ChristmasBall (sic)."

Although Hanson have teased the album will be out next year, a set release date has yet to be confirmed.

Meanwhile, the brothers have admitted they would love '24K magic' hitmaker Bruno Mars to cover their 90s classic 'MMMBop' because they think he would do the song justice.

Speaking previously, Isaac said: "People can't sing the chorus right. Most of the time they syncopate it wrong.

"But if Bruno Mars were interested, he'd probably find a way to kill it."

Whilst Taylor added: "Someone needs to either make it totally their own in a genuinely unique way, or it needs to be a band that has a sensibility for old R&B. Fitz and the Tantrums could maybe do it."
