The View's frontman Kyle Falconer has been taken to hospital with blood poisoning while on tour in Japan.
The 19 year-old star has contracted septicaemia from a blister on his foot.
One pal told today's Sunday Mirror: "He has been in and out of hospital and has been really ill with infections - particularly septicaemia.
"The medics kept him in overnight and he was given a course of antibiotics. But he has been warned to start looking after himself or he is going to end up very sick indeed."
The band are currently in Tokyo to promote their chart-topping debut album, 'Hats Off To The Buskers'.
A spokesman for the band said: "Kyle should be back on his feet for their gigs next week."
The View are set for a busy summer - they have recently confirmed a double slot at the Glastonbury Festival, and will headline the Radio 1/NME Stage at the Carling Weekend: Reading and Leeds Festivals.
