Katherine Schwarzenegger is bumping along.

One month after news broke that the 34-year-old is pregnant with baby No. 3, she and Chris Pratt confirmed the news with pics of her budding belly.

The actor, 45, posted a photo on Instagram of his wife wearing pink overalls Saturday, calling her the “greatest party planner in history.”

Schwarzenegger shared her own snaps from the bash as she cuddled with a white rabbit.

“It isn’t a party without a bunny appearance,” she captioned the slideshow Sunday.

Her and Pratt’s followers congratulated the duo on their growing family in the comments — with many convinced that Schwarzenegger’s outfit hinted at baby No. 3’s sex.

The “BDA Baby” podcast host, who is already the mother of daughters Lyla, 3, and Eloise, 2, sported plaid pink overalls at the outdoor event.

“She’s wearing pink…she must be having another girl!” one Instagram user gushed, with another noting, “This is definitely a pregnancy announcement. I’m gonna guess it’s a girl due to all the pink.”

A third, however, pointed out, “I wore every color throughout all of my pregnancies and it had nothing to do with the gender lol. Unless it was a baby shower.”

The backyard bash did not appear to be a shower, as it featured a pink bounce house and a petting zoo, with Pratt showing off Lyla and Eloise’s matching cowgirl outfits.

It is unclear whether the “Guardians of the Galaxy” star’s 11-year-old son, Jack, whom he shares with his ex-wife, Anna Faris, was in attendance.

The “What’s Your Number?” co-stars were married from 2009 to 2018 and welcomed Jack four years before their split.

Pratt moved on with Schwarzenegger in 2018, getting down on one knee the following year.

The pair walked down the aisle in June 2019, with Lyla and Eloise arriving in August 2020 and May 2022, respectively.

While Schwarzenegger has not spoken about her upcoming arrival publicly, she did tease the news in a Friday Instagram post about enjoying a “melasma-free summer … especially if you have those pregnancy hormones.”
