This kid's spelling skills are bananas. B-A-N-A-N-A-S.

New Yorker and Gwen Stefani mega-fan Norah shared a video Thursday of her 5-year-old son, Max, writing his first word: "bananas."

And as he writes each letter, it's clear where he got the word from: Stefani's catchy-to-a-fault 2004 song "Hollaback Girl."

"This year, because of Gwen's tour, I played even more music and he got really into it," Norah told Mashable. "'Hollaback Girl' is by far his favorite song." (A great choice, Max.)

"Max started kindergarten this year and he's learning to read and write," she continued. "We practice his writing every night and one day he just started writing 'bananas' all by himself and when I asked how he knew that he said it was just like in 'Hollaback Girl.'"

We are sure Ms. Stefani is proud.
