VIDEO: Behind the scenes at Victoria Beckham's Armani shoot

Victoria Beckham might not have been able to look at the 20 foot image of herself in nothing more than underwear when it was unveiled in New York yesterday, but it sure looks like she had fun filming it. Here's a behind the scenes clip of the singer-turned-designer getting that famous Posh pout just right for the cameras and talking about the build up to the Emporio Armani shoot. ‘I've worked out really hard, doing a lot of running,' says the woman who has previously admitted she hated her stomach. ‘You think I look ok but if I'm going to have to be taking my clothes off you want to tone up a bit. So I worked hard to have the confidence to do it.' Victoria also reveals her favourite part of the image - her long, Cleopatra-style ponytail. ‘Creatively I have a lot of input into the shoot. I like the hair. it's really different for me, but I like to change it up, try different looks, a radical new image.' Hmmm... does that mean we'll see the extensions come back some time soon?
