Leave it to Blake Lively to give us a baby unannouncement.

While the world has been chatting about Rihanna’s pregnancy reveal during her Super Bowl halftime performance, Lively just very casually posted a photo of her post-baby body.

“Puppy Bowl Sunday 2023,” she wrote in the caption on a series of photos posted Sunday on her verified Instagram account. “Been busy.”

In one of the pictures, Lively is seen smiling and visibly no longer pregnant.

She and husband actor Ryan Reynolds were already the parents of three daughters: James, 7, Inez, 6, and Betty, 3, when Lively went public with news of baby number four in September with an Instagram post.

“Here are photos of me pregnant in real life so the 11 guys waiting outside my home for a [unicorn emoji] sighting will leave me alone,” she wrote at the time. “You freak me and my kids out.”

Lively and Reynolds are extremely private about their family life, though she cheekily would refer to her pregnancy on social media.

In January, she posted a photo showing her toned and wearing workout gear in what appeared to be a gym with Reynolds juxtaposed with a photo of her and Reynolds in the same setting with her pregnant abdomen on display.

“Been doing @donsaladino ‘s workout program for months now,” the caption read. “Something isn’t working.’

No name or gender for the new baby has been announced. CNN has reached out to representatives for the couple for comment.
