She is currently being kept busy filming Hail Caesar! in Los Angeles but Scarlett Johansson always has time for her daughter Rose.

The 30-year-old actress enjoyed lunch in the trendy area of Los Feliz on Tuesday with the four-month-old tot and tenderly cradled Rose in her arms as she carried her back to the car.

Although she only gave birth in September, it didn’t take Scarlett long to bounce back into shape and the actress – who is married to French journalist Roman Duaric  – looked slim in black trousers, a T-shirt and trainers.

The actress revealed she got back in shape by breastfeeding, telling Barbara Walters: ‘I do the whole bit. I’m nursing and I love it. It’s the best way to get back in shape.’

She added of motherhood: ‘It’s wonderful. It’s very, very magical – and exhausting. The love is just unbelievable. It’s very overwhelming.’

‘She smells sweet, totally,’ Scarlett told Germany’s Gala magazine. ‘I can’t quite describe it, but it really makes you euphoric.’

Scarlett added: ‘It’s exhausting in the most wonderful way. I never thought how much sleeping through the night would mean to me. I still lack experience. Right now I’m just trying to manage. You have to first learn the ropes.’

One month after her little girl’s birth, Scarlett and Romain secretly tied the knot on October 1.
