Lara Stone hated being pregnant.

The 30-year-old model - who has 14-month-old son Alfred with husband David Walliams - found the changes her body went through when she was carrying her little boy ''quite frightening'' and worried she would never work again.

She said: ''Being pregnant affected my work quite early on - it's not like you can work until you're eight months pregnant. It was quite frightening seeing my body change so much.

''Yes, I did worry about the impact, because my body is my job and my livelihood.''

And though the Dutch beauty took a year off work to be with her son, she admits she was keen to get back to the catwalk as she hates ''sitting around''.

She added: ''I like working and I don't like sitting around at home, so I really wanted to get back into things.

''It's nice once the baby's here, but then I was like, 'I really want to do something again.' ''

Because the couple don't live near their families, Lara admitted she and her 42-year-old spouse are often forced to leave their son with nannies for several days when they are away working.

She told the Sunday Times Style magazine: ''My family doesn't live near and my husband's family lives a couple of hours away, and both of our jobs are so unpredictable.

''Sometimes there is nothing you can do and you have to leave him with the nanny for a couple of days.''
