Chris Pratt's daughter is Maria Shriver's biggest fan.

On Tuesday's episode of Today with Hoda & Jenna, the Jurassic World Dominion star, 42, said that his 21-month-old daughter Lyla Maria, whom he shares with wife Katherine Schwarzenegger Pratt, is "most excited" about seeing her grandmother.

"She's like a living saint. I really do believe that. She's fantastic and she's so engaged and thoughtful and caring and her house is like a welcoming retreat," Pratt told Hoda Kotb of his mother-in-law. "You just relax when you go there. It's really nice. She's super doting."

The Guardians of the Galaxy actor also revealed his family's sweet nickname for Shriver.

"We call her Mama G. And Lyla just lights up so much when we talk about going to Mama G's house," he shared. "We're like, 'Honey, do you know where we're going? Mama G's house!' And she's like, 'Ahh Mama G! Mama G!' All the kids feel that way. It probably doesn't hurt that there's giant bowls of candy everywhere."
