At one time Scarlett Johansson wouldn’t have hit the red carpet without wearing a figure-hugging dress.

But on Monday evening the 29-year-old opted for something decidedly less revealing as she attended the French premiere of Captain America: The Winter Soldier in Paris.

The actress,  who is expecting her first child, instead wore a sharp red trouser suit with a loose black top which hid her growing baby bump.

While just a few days before she had been more than happy to show off the first signs of her bump in a stunning dress, it seems she fancied keeping things hidden this time round.

Her choice of outfit was however still stunning and she wore her blonde hair piled above her head in an elegant up-do.

Keeping her look elegant she wore an 18k white gold, diamond and black onyx Etincelles necklace from Van Cleef & Arpels’ Une Journee A Paris collection.

A pair of gold peep-toe heels and a fun clutch bag featuring a pair of red lips on them complete her fashion statement.

Kevin Feige told Collider.com: ‘Well my first reaction was I was very happy for her and very excited for her.
