Boyzone singer Stephen Gately has died at the age of just 33, a message on the band's tour website said.
The Irish pop star and actor was on holiday with his long-term partner in Majorca when he "tragically died" on Saturday, according to the website.
It also said the four remaining members of the band would be flying out to the Spanish island.
The statement read: "Stephen tragically died yesterday whilst on holiday with his partner Andrew in Majorca.
"The rest of the boyz will be flying out today."
The circumstances surrounding Gately's death remained unclear but the News of the World reported he died after a night out.
Gately, who married his partner Andrew Cowles in a civil union in 2006, sent ripples through the pop music world ten years ago when he announced that he was gay.
He joined Boyzone in 1993 after answering an advert in Dublin to audition for Ireland's first boyband.
The band went on to enjoy huge success with six number one singles, but split up in 2000.
