The "Her" star, who got engaged to French journalist Romain Dauriac last year, had previously said that she was in no rush to plan her wedding. But Johansson was definitely interested in having children with Dauriac, telling the U.K.'s Daily Mail in December that she "would like to have my own family" someday.
"They say it's never the right time and I am sure that's true, but I think you have to plan it like anything else," the 29-year-old told the Mail. "At some point it is something I look forward to. I am fortunate in that I have had a long career -- 20 years -- that has been very diverse. So, you know, picking a time to plan a family feels like something that I could do and not feel as though I was missing out."
TMZ reports that Johansson is about five months along, though the actress has yet to make a statement confirming the news. Johansson was previously married to fellow actor Ryan Reynolds, but split from him in 2011 after three years.
Congrats to the parents-to-be!
