The 29-year-old actress is pregnant with her first child with fiance Romain Dauriac, a French journalist. E! News was the first to report the pregnancy.
TMZ is reporting that Scarlett is "roughly five months" into her pregnancy.
In September 2013, news broke that ScarJo and Romain would tie the knot after the actress sported a giant rock while walking the red carpet at the Venice Film Festival. "I can confirm that Scarlett and Romain are engaged. They haven't chosen a date for the wedding," her rep said at the time.
Aside from the couple's appearance at the high-profile fest, Scarlett and Romain have kept a relatively low profile, spending most of their time in New York and Paris. They've been dating since late 2012.
Scarlett was previously wed to Ryan Reynolds.
