Scarlett Johansson might be in the middle of a a very public divorce, but it’s back to business as she promotes her latest film Ghost in the Shell.

The 32-year-old actress announced her split with French journalist Romain Dauriac in January after two years of marriage and while the last few weeks has been filled with mud-slinging between the two, she was all smiles on the red carpet on Wednesday night.

It was another daring outfit for the mother-of-one, who opted for a slinky rainbow dress.

Scarlett will have a jam-packed schedule over the coming weeks as she promotes her latest action flick, with her work reportedly becoming a bone of contention between the former couple, especially now that they’re gearing up for a custody battle over their daughter Rose (three).

Romain’s lawyer Harold Mayerson said in a statement he will be petitioning for custody to live in France.

“‘He [Romain] believes that her schedule makes it impossible for her [Scarlett] to have physical custody – unless she intends to have her children raised by nannies and helpers,” the lawyer said in a statement.

The actress has remained tight-lipped on her plans for custody, but recently said she’s “very thankful” to come home to her a daughter at the end of a long day.

“You have to leave all that work stuff behind and be able to present with your kid. I am very thankful that’s my reality at the end of the day,” she told E! News.

When asked if she had any plans for a new relationship, she said: “I’m on guard because I have a young daughter. That’s something I’m more concerned about.”
