With her wasp waist and firm, toned curves, she looks sensational by anyone's standards.

Especially since this picture of Catherine Zeta Jones was taken a mere 11 1/2 weeks after she gave birth for the first time, to son Dylan.

'Lots of women look at me and think, "You bitch - it's all come off you!" says the Welsh-born actress. 'But I've been working at it.' Catherine, 31, saw her weight go up by 50lb, to more than 13 stone, while she was expecting. She has already shed most of that extra burden thanks to a rigorous regime of diet and exercise.

But the new Mrs Michael Douglas is still not satisfied with her shape, telling Vanity Fair magazine: 'I've still got a way to go.' She also complains about her 'piggy nose' and 'puffy eyes'.

Immediately after Dylan was born in August, Catherine hired a £150-a-day personal trainer and began working out seriously. She ditched the steamed puddings and pizzas which she had craved during pregnancy in favour of a healthier diet.

Catherine tells Vanity Fair: 'I ate for Wales when I was pregnant, and I enjoyed everything. I was like, "Oh, who gives a s***, I'll have another burger. Cut to, "Oh my God, my baby's out and nothing has changed! I'm still the same shape".'

She says she is such a fan of carbohydrates that she would often eat three bread rolls before dinner in restaurants, which meant that the diet presented a particular challenge. 'I'm a complete peasant. Hot bread with lots of butter and cheese - that's what I'd eat for the rest of my life, but I can't.'

Catherine, who married 56-year-old Douglas last month at a £1.6million ceremony in a New York hotel, dismisses suggestions that they fell out during negotiations over their pre-nuptial agreement.

'There was no arguing, no feud. 'If I was marrying someone of lesser fortune who was 25 years younger, I'd be doing exactly the same thing. I think pre-nups are brilliant, because it's all sorted out. Why should Michael be in a position where half of his fortune, which he's worked bloody hard for, should land in someone else's lap? It wasn't a nasty experience for me, it was like, "Thank God that's done - let's get on with it."

'It was signed and put in the bottom of a drawer, hopefully never to be seen again. I get taken care of very well.'

Their wedding was 'a really great bash' she said during a television interview. 'We are party people and we love to have fun.

'It's weird that the doorman at the building where we live now calls me Mrs Douglas and I'm like, 'Who? Oh, that's me!'.

Many ambitions remain, and she hopes to get an Oscar to compete with Douglas's tally of two, which are displayed on his mantelpiece. I want to have my Oscar up there too. He tells me not to worry; if I don't get one, I can borrow his.'
