Gisele Bündchen Allegedly Steps Out Wearing a Burqa to Conceal Identity

While Bündchen and her sister Rafaela were supposedly disguised from head to ankle as they got out of a Mercedes outside the clinic, several details point to Bündchen. PEOPLE has confirmed that the driver of the car (pictured in other photos) is Bündchen's longtime Paris chauffeur. And in other photos, one of the women is seen carrying a black Calvin Klein backpack, which is identical to the bag Rafaela had a week later when departing Charles de Gaulle airport.
Also of note is that several shots show that the women are barefoot – wearing sandals without covering stockings – which contradicts religious rules.
Representatives for Bündchen have not responded to repeated calls for comment.
According to the French magazine CLOSER, the sisters arrived in their concealing gowns at the Clinique International du Parc-Monceau on July 15, stayed overnight and returned to the Hotel Bristol the following day. Before returning to the United States, the sisters reportedly spent several days at the Sources de Caudalie, a five-star hotel-spa near Bordeaux.
The sisters were photographed leaving Charles de Gaulle Airport on July 24 with Bündchen wearing dark glasses, taking a flight to Boston.
It's a bizarre sighting of the world's highest-paid model, who has been outspoken about the hard work she puts in to maintain her famous physique.
"Like I tell my five sisters, who don't work at it very hard at all, whatever you put in, you get out," Bündchen, who is mom to Benjamin, 5, and Vivian, 2, with husband Tom Brady, 37, told Vogue U.K. in 2011. "I'm not afraid of working hard at anything, whatever it is. I just always want to be the best that I can."
