Katherine Schwarzenegger and Chris Pratt Expecting Baby No. 3

Katherine Schwarzenegger and Chris Pratt are expecting their third child together!

On June 28, a source confirmed to People that Katherine, the daughter of Arnold Schwarzenegger and Maria Shriver , is pregnant with baby No. 3. Katherine, 34, and Pratt, 45, currently share two daughters, Lyla , 3, and Eloise , 2. Additionally, Pratt shares a son, Jack , 11, with his ex-wife, Anna Faris , 47.

The same day the pregnancy news made headlines, Katherine took to Instagram to share photos of herself, Pratt and their little girls.

"Things that make me happy: A gloomy morning followed by a barn visit ☺️❤️," the expecting mom captioned her update.

Although she didn't mention the pregnancy, the Gift of Forgiveness author offered a sweet glimpse at Lyla and Eloise. In the pictures, Katherine and Pratt's daughters rode horses (and their dad's shoulders) and explored a garden.

Last month, Pratt stirred up a fair bit of contention with his fans when he neglected to mention Faris in a Mother's Day Instagram post . The Guardians of the Galaxy star included several pictures of Katherine and his mother while praising his wife for being a fantastic mom to their daughters and a stepmom to Jack.

"Forgot a mom didn't you?" one Instagram user commented.

"He should post her for the child they share. She is raising him up properly. 👏." someone else wrote.

Mother's Day Instagram etiquette aside, we wish Pratt and Katherine the best as they embark on this new chapter in their family!
