Brazilian beauty Lais Ribeiro physically jumped when a loudspeaker bellowed there was just one hour until show time.

"Butterflies just came stronger in my stomach. I'm getting very, very excited," Ribeiro, 26, tells the Associated Press.

Ribeiro knows more than most about the hidden dangers in a show such as this, where models in towering heels can injure themselves. She hurt her foot as a Victoria's Secret Angel three years ago.

"What am I scared of? I twisted my ankle and kind of broke my foot in the rehearsal three years ago. So I'm always scared of the high heels (that might make) me miss this amazing show," she says.

Security tight

Hours before last Wednesday's show began, hundreds of meters in the area around Paris' Grand Palais and the Champs Elys ées avenue were in near lockdown, barricaded with passing tourists and fashionistas alike getting frisked.

Bomb squad dogs sniffed out every single bag that entered the Grand Palais where the fashion show took place.

Paris remains in a state of emergency following last November's Paris attacks at a concert hall and various spots around the capital.
