As messages of support pour in for Cheryl Cole, her worried mother is said to be constantly by her bedside.
50-year-old Joan Callaghan was pictured looking downcast yesterday as she visited her daughter.
Cheryl is battling malaria, after catching the potentially fatal disease it is thought while on holiday in Tanzania.
She is being treated at University College London, which is home to the Hospital for Tropical Diseases, in the centre of the capital.
JLS, Nadine Coyle and Sinitta are amongst Cheryl's star pals who have tweeted messages wishing her well.
