Lisa Snowdon is "on the mend" after contracting viral meningitis.
The Marks and Spencer model, who also works as a Capital Radio DJ, was taken to hospital on Friday, hours after turning on the Christmas lights in London's Bond Street (pictured).
A friend told the Daily Mail: "Lisa was feeling rotten for a good few days.
"On Thursday night she switched on the lights and she was clearly unwell and struggling to hold it together.
"She had flu symptoms, major aches and pains and a migraine.
"She then had to go on and host a dinner. But after that she just fell apart and she went to the doctor and was immediately checked into hospital."
A spokesman for the 38-year-old, who once dated George Clooney, confirmed Lisa's hospitalisation, adding: "She is now on the mend but is unlikely to return to the Breakfast Show next week."
