The past few days have been filled with some major celebrity pregnancy announcements. From Ellie Kemper and Michael Koman to Blake Lively and Ryan Reynolds to Eva Mendes and Ryan Gosling, it seems like all our faves will be welcoming a(nother) bundle of joy in the coming months. Now, we can add Olivia Wilde and Jason Sudeikis to that list.

Wilde announced she and Sudeikis are expecting their second child in the cutest way possible — with the help of their son, Otis Alexander.

"Matching baby bumps. ✌️," Wilde captioned on Instagram, adding the holding up two fingers emoji for emphasis.

Otis turns two on Wednesday (April 20), so a sibling seems like the perfect birthday gift. At a Marimekko for Target event recently, Wilde said that Otis "loves little babies ... He has a Michael Jordan doll that he carries around sometimes. [Otis uses the doll] as either a hammer or a baby."

Congrats to the growing Wilde-Sudeikis fam! We look forward to seeing all the adorable sibling moments to come.
