It is hard to believe she gave birth just 20 weeks ago.

On Wednesday Scarlett Johansson continued to show off her trim post-baby body as she went shopping in LA.

The star went for casual chic as she dressed in a smart pair of high-waisted trousers, and тιԍнт-fitting white top.

The 30-year-old actress welcomed little Rose into the world five months ago with her husband Romain Dauriac, and the stunning star admits the tiny tot didn’t look anything like what she’d imagine but she wouldn’t change anything about her now.

Speaking in the new issue of W magazine, Scarlett said: ‘When she came out of me, I was so surprised. I had a very strong picture in my mind of what my baby would look like.’

She added, ‘And, of course, she is completely different. Perfect, but not what I’d imagined. Now, of course, I can’t picture her any other way.’

Meanwhile, the Captain America star has sprung back into shape in just 20 weeks and believes breastfeeding has helped.

Speaking about breastfeeding recently, she said: ‘It’s the best way to get back in shape. [I do] the whole bit. I’m nursing and I love it.’
