The producers of the show deemed her emotionally unstable and did not broadcast the interview. Not only was the show never aired, but the entire recording was erased.

Days later, Mulder repeated her allegations, this time to a weekly magazine in an interview conducted in her Paris apartment. Within hours of the interview, her sister Saskia arrived and took her to Villa Montsouris, a psychiatric hospital specializing in such disorders as depression, anxiety, and delirium, where she stayed for five months. The stay reportedly was paid for by Elite models president Gerald Marie, an old friend of hers and one of the accused. (It came after the BBC caught Marie on hidden camera trying to give a 15-year-old model £300 for sex, and bragging Elite Model Look competitors he would sleep with that year.)

On 11 December 2002, after suffering for years from chronic depression, Mulder went into a coma after she overdosed on sleeping pills in an apparent suicide attempt. She left no note. She was rushed to the American Hospital in Neuilly after neighbors found her passed out on the floor of the Paris apartment on exclusive Avenue Montaigne where she was staying with friends. Mulder's parents flew from the Netherlands to be by her side along with former fiancé Jean-Yves Le Fur. Le Fur was reportedly one of the people who found Mulder unconscious after arriving at the apartment after Mulder had not answered several of his telephone calls. She awoke from her coma the next day.

In the summer of 2004, Mulder decided to re-enter the music industry. She worked with Daniel Chenevez of the Niagara group to create the self titled CD Karen Mulder. She gave birth to a daughter, Anna, on 30 October 2006.

On 1 July 2007 she returned to the catwalk at the Dior Autumn/Winter 07/08 Couture Collection in Paris, modelling alongside Naomi Campbell, Linda Evangelista, Helena Christensen, Amber Valletta, Shalom Harlow and Stella Tennant.

On 1 July 2009, the Daily Mail reported that Mulder was arrested in Paris for threatening to attack her plastic surgeon. Though the exact nature of the type of plastic surgery is unknown. And the outcome of the it was never reported, Karen Mulder has been keeping a low profile since this whole ordeal.
