Lara Stone has body worries.

The supermodel - who has a 14-month-old son, Alfred, with comedian David Walliams - is trying to ''accept'' her new body after refusing to restrict her diet during pregnancy.

She told NET-A-PORTER.COM's digital magazine The EDIT: ''I wasn't exercising a lot. I was just eating whatever I wanted; I wasn't being careful about that at all. I was huge.

''It's the way it is.

''Everyone's got arm flab or saggy boobs.

''I'm just trying to accept it right now. And it's OK, because the things women can do with their bodies are amazing.''

Following the birth, Lara, 30 - who is currently signed to an exclusive contract with iconic jeans brand Calvin Klein - found her perspective on having the perfect body had changed.

She said: ''You have to sit there and really think about it. 'Oh, I grew this little person's fingernails in my tummy.' After that, do you really give a s*** about arm flab? Because I don't.''

Meanwhile, the stunning blonde - who has been married to David, 42, since 2010 - is also getting used to being a mother to her young son.

She said: ''He's this huge monster - in the loveliest way. He's very strong-minded and he knows exactly what he wants to do, and if it's not right he'll have a huge tantrum.''
