"I'm not this girl all the time," insists Gisele Bündchen of her supersexy Victoria's Secret persona. She is for at least one week a year, though, as she readies for the brand's annual fashion show (airing on CBS Dec. 5 at 10 p.m. ET). The supermodel, 26, offered PEOPLE an exclusive look at what happens before the wings—and the cameras—go on.
Fitting at the Victoria's Secret Design Studio, New York City. Gisele gets her wings—30-in. ostrich feather creations. Unlike at past shows, she says, "these weigh less than my little dog! My back is thanking you!"
One complaint. "I don't see any covering for my booty," she tells the stylists. As senior Angel this year (Heidi Klum
is out with her new baby), Gisele requests a costume tweak. "A bit longer would be just beautiful." A piece of fabric is added.
In between costumes, she gets a bit cranky. "I'm naked and it's freezing!"
With a break between gigs, Gisele visits the Kisêdjê tribe in her native Brazil to raise awareness of deforestation in the Amazon's Xingu River region.
Waiting to board a private jet to L.A. She ignores the other models smoking outside the Newburgh, N.Y., hangar. "When I quit smoking [in '03], I gained 15 lbs. So? I prefer myself this way. Nothing is worth your health."
Reading Tuesdays with Morrie
on the plane. "It's so sad, and I'm only on page 68!"
Lunch. Cleans the tray: salad, steak, peas, potatoes, brownie. Then she eats a neighbor's brownie.
Arrival in Burbank. Greeted by a phalanx of photographers.
At Grauman's Chinese Theater for the key to Hollywood.
"Barbecue at my friend's house. I don't want to feel like I'm [just] working and don't have a life!"
At the Renaissance Hotel. Multitasking: breakfast of eggs and bacon—and a pedicure. "We have to have beige nails. It's sexy, natural."
Eyebrow emergency! A bad reaction to a brow waxing puts Gisele "not in a good mood," warns a rep, keeping photographers away.
Eyebrow situation under control, Gisele talks to reporters, gets her hair styled and eats half a tuna sandwich. "If I don't eat before the show, then you wouldn't see me in the show," she says. "'What happened to Gisele?' 'She passed out.'"
Kodak Theater, where the first of two fashion shows is taped. What goes through her mind on the catwalk? "[Going out,] I focus on a light, then I focus on the wall coming back. That's all I think about when I walk."
"I almost had a heart attack! My skirt got stuck in my shoe for the Scottish outfit. I'm like, 'Skirt, you're disappointing me!'"
Second taping. No gaffes.
Teddy's, a club in Hollywood. Gisele orders a Femme Fatale (vodka, pineapple and Chambord) and some hamburgers at the afterparty, but "I never stay long. I shoot tomorrow, then I leave to Brazil, then Ibiza, then Paris. It's nonstop!"
