Singer Cheryl Cole is in hospital being treated for malaria, her spokesman has confirmed.
The 27-year-old X Factor judge and Girls Aloud star was admitted to hospital after reports she had fainted during a photoshoot at the weekend.
On Monday, it was confirmed Cole had cancelled all of her work commitments this week on the advice of doctors.
Cole recently returned from a break in Tanzania, on the east coast of Africa, with friend and dancer Derek Hough.
Mosquito bite
The Sun reported Cole collapsed at a photoshoot for her second solo album on Saturday and was diagnosed with exhaustion and gastroenteritis.
The early symptoms of malaria include a headache, aching muscles and weakness or a lack of energy. This means it can be confused for other conditions like exhaustion or flu.
Malaria is transmitted by an infected mosquito and it only takes one bite to contract the disease.
Cole, who is currently filming the audition stage of ITV talent show The X Factor, has had a turbulent year.
She split from her husband, England footballer Ashley Cole, in February and filed for divorce three months later.
Since then, she has been kept busy touring as a solo act for the first time, supporting hip-hop band Black Eyed Peas, and recording her second album.
The Girls Aloud star is also scheduled to play high-profile shows at the V Festival in August.
