She noticeably didn't include her half-brotherJoseph Baena, 21, in the tribute post and people were quick to point it out.  Joseph is the “The Terminator” star’s son with Mildred Baena, Schwarzenegger’s former housekeeper.

Katherine, 29, captioned the photo, "I love them so much #nationalsiblingsday."

When called out by a commenter, the fiancée of Chris Pratt, wrote back to the social media user: "Saw in your profile it says 'god always'. Just wanted to remind you of Gods presence in all of our lives and even in yours as you come spreading hurtful words and judgment."
