Scarlett Johansson is pregnant! The actress is reportedly expecting her first baby with her fiancé, independent advertising agency owner, Romain Dauriac.

It has only been about six months since Johansson and Dauriac got engaged in August 2013. The blonde star and her French beau walked the red carpet together at the Venice Film Festival in September 2013 for Johansson's movie, Under the Skin. It was when their representative made the announcement that they were engaged, and she showed off the engagement ring - a vintage Art Deco piece - on her finger. They have yet to announce a wedding date, and as Johansson previously said in interviews, she is not in a hurry for it.

The two went public with their relationship back in November 2012, and have been a low-key, but tight couple. They got together shortly after Johansson's relationship with Nate Naylor, which lasted a year, ended. The Lost in Translation actress was also previously married to actor Ryan Reynolds. They married in 2008, separated in 2010, and officially got divorced in 2011.

Johansson is said to be about five months pregnant, which brought up concerns about her role in the latest Avengers movie, Age of Ultron. The sexy star plays Natasha Romanov, also known as Black Widow, in the Avengers franchise, which requires her to don skintight, black bodysuits, and do action-packed scenes. Filming for the new movie is said to be starting in April, and by then, Johansson will be in the middle of her pregnancy. A source told E! News that her scenes will be fast-tracked to make it work. The studio has not made any official announcement about the issue however.

At the moment, Johansson is busy with promotional duties for Captain America: The Winter Soldier - another movie under the Avengers franchise - where she plays the same role. It is set to come out in theaters on April 4.
