She may be known for her slim physique, but Victoria Beckham thinks she looks "really awful naked."
Having three children and then losing the baby weight has been tough on her body, Beckham, formerly known as Posh Spice, tells the Australian edition of Harper's Bazaar.
"I've got so much saggy skin on my stomach," she says. "I might fit into jeans, but trust me, I look really awful naked."
Beckham, 32, adds that she has "no bum at all," despite her appearance in ads for her new fragrance, which she credits to the magic of retouching.
She also says she got her new, short haircut because "I got sick of those bloody hair extensions."
But these days Beckham is focused on other things besides her looks, such as fashion design and her family – her English soccer-star husband David Beckham and their three sons, Brooklyn, 7, Romeo, 4, and Cruz, 19 months.
Since giving up her music career in 2004, the former Spice Girl has designed jeans and sunglasses, and recently released a fragrance with her husband called Intimately Beckham.
And lately, she's been sharing her passion for fashion with another famous mom: Katie Holmes. The two were spotted together at last week's Chanel show
Her family life is strong too, Beckham says, despite rumors two years ago of her husband's infidelity. "We've had a fair amount of c– thrown at us, and it can be very upsetting," she tells Bazaar.
"If it doesn't kill you, it makes you stronger. I think we are a very strong family. It's easy to give up, and a lot of people do. We love each other to pieces. You work things out if you really love someone."
Still, all the scrutiny may have soured her a bit on the idea of fame. "Do I wish I could be anonymous?" she says. "Of course. I don't need to feed my ego that way anymore."
