Over the weekend, Katherine‘s mom Maria Shriver gushed about helping plan Katherine and Chris Pratt‘s wedding.

“[Wedding planning is] fun,” Maria shared with ET. “I think it’s always great to celebrate love. It’s the most important thing in the world. You learn unconditional love ideally from your mother and then if you find it in your life, you’re blessed.”

FYI: Katherine is wearing a TNA for Aritzia shirt.
