Katy Perry opened this year's Victoria's Secret fashion show in spectacular style tonight. The Teenage Dream star pulled out all the stops for her performance, which saw her model two eye-popping outfits from designer Todd Thomas. With her killer curves and penchant for wearing provocative costumes, Katy certainly seemed a natural fit for the famous lingerie label.

Akon also performed at the show, singing his new single Angel. Of the models, he said: 'You see them in person, it's like a whole other thing. They're amazing, they're beautiful.'Victoria's Secret 'angel' Adriana Lima, 29, opened the show in a giant set of wings, making her return to the catwalk for the first time since giving birth to daughter Valentina a year ago. Her first fashion show for Victoria's Secret was in 1998 and since being contracted as an 'angel' in 2000.

'To be back in shape for the fashion show, it wasn't easy for me,' she told USA Today backstage. 'I really worked very hard.'The brunette, who gained 50lbs during her pregnancy, certainly looked back on form as she modelled the $2 million Bombshell Fantasy diamond bra she first debuted last month. Designed in collaboration with Italian jeweller Damiani, and containing more than 3,000 jewels, the piece took six craftsmen 1,500 hours of work to complete.

Adriana was joined by Alessandra Ambrosio, Karolina, Chanel Iman, Candice Swanepoel, Isabel Goulart and Selita Ebank. Karolina Kurkova, 26, who wore an animal print set with peacock wings, admits that keeping a Victoria's Secret-worthy figure is tough. 'I try to eat organic all the time,' Kurkova said. 'I don't eat white sugar, white flour, processed food.'

There were a few notable absences from the parade. Heidi Klum this year decided to bow out of her affiliation with the Victoria's Secret label after 13 years. 'Obviously, it's different,' said Ambrosio, when asked about Klum's departure. 'I miss the way she walks and her laugh and her personality,' Lima said.

Miranda Kerr, who is expecting her first child with actor Orlando Bloom, sat the night out too. Pregnant Doutzen Kroes, who married to DJ/producer Sunnery James this week, was also understandably otherwise engaged. The Victoria's Secret Fashion Show screens on CBS on November 30 in the U.S.
