Olivia Wilde and Jason Sudeikis have welcomed their new baby into the world! The engaged couple's son, Otis Alexander Sudeikis, was born on Wednesday (April 23) in New York City. The "Drinking Buddies" actress share a photo of her new baby on her Twitter. "Ladies and gentlemen, Otis Alexander Sudeikis has LEFT the building! (I'm the building)," the actress tweeted hilariously.

Less than 24 hours after Wilde announced that she and Sudeikis welcomed son Otis, she joked about her firstborn on her Twitter on Thursday. "Having an infant son alerts me to the fact that every man, at one point, has peed on his own face. #awesome," she joked to her 1.36 million Twitter followers.

Olivia Wilde and Jason Sudeikis announced their engagement in January 2013 and announced Wilde's pregnancy in October. Last summer, in an interview to InStyle, Wilde said some very sweet things about her relationship with soon to be husband Sudeikis, whom she began dating in November 2011. "I like having a real partner," Wilde explained. "It's the model I grew up with. It's part of why I was able to take so many chances in my life, because I felt like someone was watching my back. I could never imagine life without someone I respect, someone who offers me infinite possibilities."

"There are spikes and dips and plateaus in this business. I've seen couples fall apart through it, and it is heartbreaking," she continued. "You wonder what will happen-will he love me if I'm not as successful? Will jealousy kill us? I know there will be times when Jason is working more than I am, but I'm actually excited by that. I'm excited by what he will become, what depth he has."

Meanwhile, Wilde's husband is busy on the set of his new movie Tumbledown with also starring Rebecca Hall.
