Just in time for the Olympics, Victoria's Secret opened its first U.K. store in London earlier this week. But what does it take to look like the models in the sexy TV ads?

As for our all-time favorite, Brazilian beauty Adriana Lima, the 31-year-old mom works out with a personal trainer twice a day leading up to the annual fashion show. For nine days before the show, she gives up solids for protein shakes. Then, 12 hours before the show, she stops drinking altogether. "No liquids at all so you dry out, sometimes you can lose up to eight pounds just from that," she told the Telegraph last year (via The Daily Mail). 

Orlando Bloom's 29-year-old wife Miranda Kerr -- who wore the $2.5 million Fantasy Treasure bra at last year's show -- says she practiced yoga throughout her pregnancy. "I am a blood type A and more often than not I eat specifically for my blood type. I also eat low GI, high alkaline foods, drink filtered water and eat mostly fresh produce and very little meat," she has said.
