Guess who has a bun in the oven? That's right, pouty-lipped actress Scarlett Johansson! The actress and SodaStream spokesmodel, 29, is reportedly expecting her first child.

The news that the lovely and talented actress is going to take on the new (and very important) role of mommy was confirmed by a source to E! News.

Scar Jo and fiance Romain Dauriac, 32, have been engaged for six months. They began dating back in November of 2012, after she ended her relationship with non-celeb Nate Naylor.

Dauriac is a French journalist and the couple has been living in his native France. They confirmed their engagement last September.

Johansson recently said that she and Dauriac were not planning to speed down the aisle and that she wasn't anywhere close to sorting key details yet. She seemed content to have a longterm engagement. Now that she is expecting, she is doing things in reverse, which is totally modern of her!

Johansson, who has a twin brother, was previously married to hunky actor Ryan Reynolds. They divorced in July 2011 after three years of marriage. He then went on to marry Blake Lively, who once dated Leonardo DiCaprio, in September 2012. We know -- it's a tangled dating web these celebs weave.

That said, congrats to the couple on their bundle of joy to be. We bet Scar Jo will make a terrific mom!
