A spokeswoman for the "Tron: Legacy" actress confirms the couple welcomed son Otis Alexander on Sunday.
Wilde posted a message on Twitter Wednesday with a photo of her cuddling the newborn. It says, "Ladies and gentlemen, Otis Alexander Sudeikis has LEFT the building!" and then notes in parentheses that she's the building.
The 30-year-old "Rush" and "House" actress is engaged to the 38-year-old "We're the Millers" actor and former star of "Saturday Night Live."
It's the couple's first child.
