Shriver’s tight bond with her granddaughters

In a new interview, Schwarzenegger spoke about her mother and her tight relationship with her grandkids. Schwarzenegger recently launched a clothing collaboration with Cleobella, quoting some inspiration from her mom and her daughter, who often wear matching clothes. “My mom and my older daughter, Lyla, try to do everything matching. So I'm really excited as we go into this holiday season that they have another outfit to be matching in, because they are very connected in that way.”

Schwarzenegger explains that she also has matching outfits for her two daughters. “So these matching outfits make a very easy milestone moment of them also entering into their own personalities, which reminds me a lot of my sister and I as we were growing up,” she said “Also just documenting everything as a mom is fun.”
