Chris Pratt has finally learned how to spell his wife's last name.

On Wednesday, the 42-year-old actor appeared on a special primetime episode of Jimmy Kimmel Live, and promised to be honest when the host asked if ever has trouble spelling Schwarzenegger.

Pratt and Katherine Schwarzenegger have been married since 2019.

"I've learned now," he quipped. "It's a long name."

It's a name that the couple has passed on to their two daughters, 1-year-old Lyla Maria Schwarzenegger Pratt, and newborn Eloise Christina Schwarzenegger Pratt.

"There's a lot of letters in these children's names," Pratt joked of his daughters. The actor is also dad to his 9-year-old son, Jack, with his ex-wife, Anna Faris.

Pratt's daughters won't have to worry about hyphenating, as the actor explained, "Schwarzenegger is the second middle name. We didn't hyphenate our names. It's a middle name."
