How DID she do it? Scarlett gave birth to her first child in September last year, and has snapped back into shape

The star’s look was completed with gold strappy heels and her short blonde hair slicked back.

While she is currently juggling being a new mom and a major movie star, you won’t hear Scarlett complain about.

Scarlett recently revealed that she hates when actors making a big deal out of parenting.

She gave birth to her daughter Rose – her first child with French husband Romania Dauriac – last September and will admit her life has changed a lot since becoming a mother.

Unlike many of her Hollywood peers, Scarlett won’t be making any ‘grandiose statements’ about her experience of motherhood because she doesn’t think it’s appropriate.

In an interview with Australian website News.com.au, she said: ‘I always really hate it when actors or people in the spotlight make giant grandiose statements about parenthood because it’s so, so personal.’

Touching on the changes Rose has had to her working schedule and her home life, Scarlett – who splits her time between her homes in Paris and New York City – added: ‘I have a greater responsibility now so that will definitely affect my schedule. Before (Rose), I just made the choices that were affecting me but now I’m responsible for somebody else.

‘Eventually I will have to work less and it might even make me more discerning.’

Although Scarlett believes there will come a time when she will have to work less because she’s a parent, at the moment the 30-year-old actress says her work has been inspired by seven-month-old Rose.

Scarlett – who returns as Natasha Romanoff/Black Widow in Marvel movie ‘Avengers: Age of Ultron’ – explained: ‘I think it will hopefully enrich my work as well as my understanding of myself. That’s the hope anyway, you never know.’
