Australian supermodel Miranda Kerr said that she still get nervous walking on her underwear sometimes.

Most would think that Miranda Kerr is used to wearing sexy lingerie, being one of the pin-up girls of the undergarment giant Victoria's Secret. However, the Aussie supermodel said that she still get nervous parading herself in bra and panties but said that she tries to have fun in the runway.

Miranda Kerr has shown acres of flesh during the Victoria's Secret fashion show and during photo shoots. It is surprising to learn this fact since she is very confident.

"For me personally, I try not to think about it too much and just try to have fun with it and have a good time. I love runway, especially Victoria's Secret runways, they're really fun, we get to express our personality and have fun up there on stage. I also like studio shoots too, they're really fun. It's like working with family," Miranda said to MSN.

Currently promoting the sexy summer collection of Victoria's Secret, Kerr said that she adored the collection, especially the multi-way bra. The model added that it is essential to have a good bra in your wardrobe.

Miranda Kerr will be flying to Sydney by the end of the month for her free yoga class as part of the IWIYW challenge for the Earth Hour. The model was appointed as ambassador of the event.

Earth Hour is an annual global event organized by the World Wide Fund that is held every last Saturday of March. Every year, the organization asks every household to participate by turning off their lights for an hour in order to raise awareness about the need to conduct immediate action against climate change.

Sydney pioneered the Earth Hour in 2007 as organized by WWF and Sydney Morning Herald in 2007. That year, 2.2 million Sydney residents participated by turning off all of their non-essential lights. Following Sydney's lead, other cities adopted the concept in 2008.

Miranda Kerr, who is married to actor Orlando Bloom, is current in the United States to attend to her modeling duties while Orlando is wrapping up the shoot for the movie "The Hobbit."
