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!
