Scarlett Johansson showed off her blossoming figure at a red carpet event on Thursday (13Mar14) as her Avengers boss revealed he is arranging the next film's schedule around her pregnancy.

Reports surfaced earlier this month (Mar14) suggesting the actress is expecting her first child with fiance Romain Dauriac, but the Lost in Translation beauty has yet to confirm the baby news.

She walked the red carpet at the Captain America: The Winter Soldier premiere in Los Angeles, and looked glowing as she showed off a curvier figure, hiding any signs of a burgeoning baby bump in a cleverly-cut monochrome outfit.

However, Marvel Studios President of Production Kevin Feige has revealed news of the star's impending motherhood means shooting schedules for upcoming blockbuster Avengers: Age of Ultron had to be changed.

He told, "Well my first reaction was I was very happy for her and very excited for her.

"My second reaction was we've got to move some pieces on the chess board around schedule-wise. But we didn't change the script at all, which is sort of the most important things for us in terms of the storyline."

The Avengers sequel is due for release next year (15).
