Chris Pratt Jokes He Has Finally Learned How to Spell Schwarzenegger: 'It's a Long Name'

Chris Pratt celebrated his third wedding anniversary with wife Katherine Schwarzenegger Pratt on Wednesday

Chris Pratt is sounding it out.

The 42-year-old Jurassic World Dominion actor appeared on Jimmy Kimmel Live! Wednesday, and at the start of the interview, host Kimmel, 54, congratulated Pratt on welcoming his second daughter with wife Katherine Schwarzenegger Pratt last month, baby Eloise Christina Schwarzenegger Pratt. (They also share daughter Lyla Maria, 22 months, and Pratt is also dad to son Jack, 9½, with ex-wife Anna Faris.)

"Can I ask you a question? Please be honest," Kimmel said. "Do you ever have trouble spelling Schwarzenegger?"

After a laugh, Pratt answers, "I've learned now. Yeah, I've learned now."

Kimmel recalled about Katherine's famous dad Arnold Schwarzenegger, "I have to tell you, when he was governor and I used to have to write it a lot when we were doing the monologue, and every time I have to really think about it."

"Yeah," said Pratt, "it's a long name. There are a lot of letters in these children's names. Schwarzenegger is the second middle name. We didn't hyphenate the names, it's a middle name, but I guess maybe that's semantics."

Kimmel then asked, "Did Arnold insist on that? Was he like, 'My name needs to be in there'?" Responded the Terminal List star, "No, no, that was Katherine. She's got his strength, and what mama says goes."
