>> Alessandra Ambrosio has taken a couple of turns on the Spring 2011 catwalks — the latest was at Giles, where she wore her bread and butter: a bikini. "I wake up and read [show stylist] Katie [Grand]'s message on my phone — 'Are you okay wearing a bikini?'" she told The Cut. "I had to think second thoughts about what I was going to have for breakfast. [But] I'm like, 'I guess.' Because I'm Brazilian and I do Victoria's Secret, it wouldn't be polite to say I'm not okay. As long as it's not a G-string, I'm okay. I'm a mom now: I can't [do G-strings]." See Ambrosio, Jessica Stam, and more doing the backstage thing during London Fashion Week — we've got snaps from Christopher Kane, Erdem, Giles, Mary Katrantzou, Matthew Williamson, Marios Schwab, Mark Fast, Peter Pilotto, Pringle of Scotland, Richard Nicoll, Jonathan Saunders, Topshop Unique, and Vivienne Westwood.
