Status Quo guitarist Rick Parfitt has died from a severe infection.
The 68-year-old's manager has confirmed he passed away in Spain at lunchtime after being taken into hospital on Thursday,
He'd been suffering complications with a pre-existing shoulder injury.
The statement said: "We are truly devastated to have to announce that Status Quo guitarist Rick Parfitt has passed away at lunchtime today.
"He died in hospital in Marbella, Spain as a result of a severe infection, having been admitted to hospital on Thursday evening following complications to a shoulder injury incurred by a previous fall.
"This tragic news comes at a time when Rick was hugely looking forward to launching a solo career with an album and autobiography planned for 2017 following his departure from Status Quo's touring activities on medical advice.
"He will be sorely missed by his family, friends, fellow band members, management, crew and his dedicated legion of fans from throughout the world, gained through 50 years of monumental success with Status Quo.
"Rick is survived by his wife Lyndsay, their twins Tommy and Lily and Rick's adult children Rick Jnr and Harry.
I cannot describe the sadness I feel right now. To many he was a rockstar, to me he was simply 'Dad', and I loved him hugely. RIP Pappa Parf— Rick Parfitt Jnr (@RickParfittJnr) December 24, 2016
"No further comment will be made at this time and Rick's family, and the band, ask for their privacy to be respected at this difficult time."
The Surrey-born guitarist had been dogged by health concerns for years, most recently pulling out of the band's tour following a heart attack over the summer.
Manager Simon Porter said at the time Parfitt had "died" for several minutes, which had affected him mentally.
He first suffered a quadruple heart bypass in 1997 after touring with the band for decades, during which time he had weathered drink and drug problems.
As a member of Status Quo, Parfitt found success globally with hits such as Rockin' All Over The World and Whatever You Want.
In 2015, the band passed a milestone enjoyed by only a handful of musicians - spending a total of 500 weeks in the UK album charts.

Following news of his death, their official website updated to show a full-screen picture of the rocker on stage with his guitar.
Doctors first informed Parfitt his lifestyle of rock and roll debauchery could cost him his life after his first bypass in 1997.
But, despite cutting down on his vices, he vowed not to become a "born-again Christian" and still enjoyed the "odd pint".
He joins a long list of celebrated musicians to have died in 2016 - including David Bowie, Prince and Leonard Cohen.
