The British supermodel who sparked baby rumours when she showed off a slightly rounded stomach in London at the weekend insists she has gained some weight “in the right place”.
She said: "I am a woman now. It's true. Honestly, I've never worn a bra in my life. Ever! It's so awful, even my friends are phoning me up and saying, 'Are you pregnant?'
"And I'm like, 'No! I just put on a couple of pounds and they went in the right place.' Isn’t that weird?”
The formerly gaunt star – who is launching a range of underwear for British high street Topshop - says she can now “fill a B-cup” and is wearing bras for the first time.
She adds: "I've just started wearing bras. It's a miracle. Great timing for my lingerie collection. I've just grown breasts."
Kate loves her body, but is concerned her Kills rocker boyfriend Jamie Hince might not be happy with her new curves.
The 35-year-old beauty added to New York magazine: “My boyfriend might not like them. I’m a bit worried”.
The model also lashed out at Tom Cruise and his wife Katie Holmes, claiming they cut in front of her and designer Stella McCartney at last year’s Met Ball in New York.
Kate had been waiting in line for more than an hour.
She said: "Tom and Katie just walked right up to the front, and we were like, 'Who the f**k are they? They're not even in fashion!' "
