A very pregnant Olivia Wilde was recognized as "House of Cards" actress Kate Mara while walking through NYC, despite her huge baby bump and fast-approaching due date, Olivia Wilde revealed on her Twitter account!

"Hey @_KateMara - I just got recognized as you. It took every ounce of restraint not to say "damn straight!" and just bask in your glory," pregnant Olivia Wilde wrote on Twitter, The Daily Mail reports

"House of Cards" star Kate Mara, 31, quickly replied: "Hey @oliviawilde That makes me WILDEly happy. I'd like to be recognized as you.. any day. Food baby and all."

Olivia Wilde, 30, is currently pregnant with her fiance Jason Sudeikis' baby. Olivia Wilde told People magazine at the 2014 Golden Globes that her baby due date is "at the end of April." But Wilde also admitted to Ryan Seacrest from E! that her baby boy could come a little later, quoting "Star Wars."

"May the fourth be with you," Olivia Wilde said, explaining that's how she remembers the possible due date of her first child with Sudeikis.

Perhaps the reason Olivia was confused for Kate was because her baby bump was hidden beneath a big coat during the chilly NYC day, making her look more like the petite actress. Olivia was also wearing large sunglasses, obscuring most of her features.

"It's great - I've never had boobs before!" the actress joked to Seacrest when he complimented Wilde's tight, emerald sequined Gucci gown at the 2014 Golden Globe Awards, which showed off her growing belly.

"Until about a week ago, I just looked fat," she admitted. "I wanted to be like, 'I'm not fat, I'm pregnant!'"

Wilde, 29, and Sudeikis, 38, are planning to marry in upstate New York, with a wedding this spring, E! News reports. Wilde began dating Sudeikis in November 2011, and they became engaged in January 2013. The couple announced they were expecting in October 2013.
