Usually pretty tight-lipped about her private life, it's no surprise that Scarlett, 29, has declined to comment on the pregnancy speculation, however she added fuel to the fire recently when she said nothing would get in the way of filming for her new movie.
"Everything for Avengers 2 we're full steam ahead. We start shooting in three weeks and I'm stunt training and we're good to go," she told The Huffington Post.
"You know, I think it's something that is [laughing] hard to talk about, exactly. You know, trying to skirt around your question exactly [laughs] - and, you know, doing a poor job of it. But, you know, like I said, everything is exactly on schedule … Everything is going just fine."
Scarlett's producer also appeared to confirm a pregnancy when he told Collider: "My first reaction was I was very happy for her... We didn't change the script at all... 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."
Scarlett became engaged to French journalist boyfriend Romain Dauriac last year. She was previously married to actor Ryan Reynolds.
