Hollywood's in the middle of popping out babies at the same rate its popping out movie reboots. Case and point, Olivia Wilde is the latest star to announce she's pregnant. Last week Megan Fox revealed she was pregnant with a baby which she officially confirmed is not Shia LaBeouf's and Blake Lively was revealed to be expecting her second child with Deadpool himself Ryan Reynolds.  

Wilde, star of HBO's Vinyl (set to return for season two), made the announcement on Instagram, as celebrities are wont to do these days. On Monday she posted an adorable black-and-white photo of her almost 2-year-old son Otis and her side by side showing their tummies with the caption: "matching baby bumps."

Like Lively and Reynolds, this is the second child for Wilde and fiancé Jason Sudeikis, who will be lending his voice for the Angry Birds animated film.

Wilde told People Otis had had some practice being a big brother.

"[He] loves little babies," said Wilde. "He has a Michael Jordan doll that he carries around sometimes. [He uses the doll] as either a hammer or a baby."

In other baby news yesterday relationship goals couple Chrissy Teigen and John Legend announced the birth of their daughter Luna on Instagram. The couple used the photosharing app to first announce they were expecting last fall.
