On Monday, K-pop boyband Seventeen are turning 10 years old, and they're celebrating by releasing a long-awaited new album.
Called Happy Burstday, it features 16 new tracks including three group songs and 13 solo songs and is their first full-length album in nearly three years.
Seventeen, which boast a whopping 13 members, have had a remarkable 12 months, including making history as the first K-pop act on Glastonbury's main stage last summer.
Unlike most Korean pop acts, they don't do collaborations - and they also write and produce their own material.
Not much information has been provided about the new album yet, but a teaser video on the band's social media channels revealed a cake with candles spelling out "Happy Birthday", before transforming into the title, Happy Burstday.
"New tour, new unit single album, new Seventeen content... and more to come," it promised fans, with press notes suggesting the band is ready to "embrace a fearless new era" as they enter their second decade.
