Two BBC presenters were robbed in a hotel room at the Cannes Film Festival.
Susannah Constantine and fellow What Not To Wear host Trinny Woodall were on the French Riviera filming a new series.
The robbers broke in and drugged them with chloroform while they slept, before stealing credit cards and jewellery.
A BBC spokeswoman said Woodall and Constantine were unhurt but deeply shocked by the robbery.
"They woke on Monday morning last week to find that cash and jewellery had been stolen from the room where they were sleeping. They reported the incident to the local police and then travelled home that day as they had planned.
"It was a horrible shock for the girls but fortunately neither was hurt by the ordeal. They both want to put it behind them," the spokeswoman said.
There was no evidence the pair had been drugged and the door to their bedroom was not forced open, she added.
But a friend of Constantine, a former girlfriend of Viscount Linley, told London's Evening Standard newspaper: "They woke up one morning and their hands felt sticky, there was a funny smell in the room and they both felt hungover.
"Trinny doesn't drink at all and Susannah doesn't drink enough to make much of a difference. It transpired they had been chloroformed and all their jewellery had been stolen."
Woodall and Constantine were in Cannes for the festival to film a special edition of their fashion makeover show. In the programme the pair take a member of the public and point out their fashion mistakes before giving them cash to revamp their wardrobe.
