(CNN) — Olivia Wilde and Jason Sudeikis are growing their family.
The couple, who announced their engagement in January, are expecting their first child together, a rep for Wilde confirmed to CNN.
The 29-year-old actress hinted this year that she and Sudeikis, 38, were open to having children, although there wasn't a firm plan in place.
"We've discussed all our ideals and hopes. I can't wait for children," the "Rush" star told Marie Claire in March. "I'm open-minded about how many, but three, which I love, is like a little party. ... (T)here's no strict plan for anything in my life. What happens, happens."
But even then Wilde said she knew her husband-to-be would make a great dad. "He's so good with kids," she told the magazine of the former "Saturday Night Live" entertainer. "I've never before experienced looking at someone and thinking, 'That's who I want to raise a child with.' "
On Twitter, Wilde has been inundated with congratulations since Sunday's announcement.
"WOW. You guys are awesome. So kind," she tweeted. "Thank you thank you thank you! PS. Babies eat mostly salsa right?"
