Alessandra Ambrosio has a big job for Thursday: opening the 2009 Victoria's Secret Fashion Show, which will be held at New York's Lexington Avenue Armory. We can boast a special connection to London, as wing man Alexander Koutny is a Central St Martins grad.

What to expect at the show? How about a bit of sci-fi. With show sections including Magical Journey, All Aboard, Pink Planet, Enchanted Forest, Romantic Journey and Star Trooper, we expect to see fashion-week catwalk trends play out on the VS runway.

This is also the first year for Behati Prinsloo to don wings, and with a gaggle of additional models (Caroline Trentini, Isabeli Fontana, Liu Wen, Chanel Iman and Rosie Huntington-Whiteley, to name a few) led by host Heidi Klum, we're sure this will be a bombshell blowout, as usual.
