The 29-year-old blonde bombshell walked the red carpet for the Captain America: The Winter Soldier premiere in Hollywood on Thursday, and debuted a tiny, almost unidentifiable, baby bump.

The actress stunned in a Giorgio Armani Prive top and skirt, Christian Louboutin heels and Van Cleef and Arpels jewels. It was also hard to miss her gorgeous vintage Art Deco engagement ring.

Johansson, who is about four months along, got engaged over the summer to Romain Dauriac, a French journalist. The two made their relationship public in November 2012.

While Johansson has yet to confirm her pregnancy, Kevin Feige did. The producer of The Avengers: Age of Ultron spilled the beans after Collider.com asked him for his reaction to the news.

"Well, my first reaction was I was very happy for her and very excited for her, and my second reaction was we've gotta move some pieces on the chessboard around schedule-wise," Feige said of Johansson who stars in the film.

"But we didn't change the script at all, which is sort of the most important things for us in terms of the story line. I think the goal is for us to sit here talking about the fact that you would never know that Black Widow was pregnant during the filming of the movie when you see the final version of Avengers 2."
