Hilarie Burton Celebrates Son Gus' Fascination with 'Elvis' Movie as He Starts 7th Grade

Hilarie Burton is loving the person her son is becoming.

The Walking Dead actress shared a photo of Gus with his hair slicked in an Elvis-like fashion and a varsity-style jacket with skinny jeans and black boots on Instagram.

"Seventh grade won't know what hit em! #firstdayofschool," Burton captioned the shot, where the 12-year-old had his hands together as though he was clapping as he laughed.

Gus's look was inspired, in part, by his new obsession with Baz Luhrmann's Elvis film.

The night prior, Burton shared an Instagram carousel of photos and videos, reflecting on her son's love of both the film and Elvis Presley himself.

"Our son starts 7th grade tomorrow. And here he is, watching @elvismovie for the 12th time (no joke!), tears in his eyes," she wrote.

"We've cried pretty much every viewing. I'm gonna need everyone to tell @bazluhrmann how much I love him for making this movie," she wrote. "Gus went through a massive Elvis phase when he was 6. We listened to @sxmelvisradio every day. Obviously, his hair and wardrobe were influenced."

Burton — who is also mom to daughter George Virginia, 4 — went on to share that Gus once "was brave enough to get up in front of the school with his raspy little voice and sing #foolsrushin. It was little kid fandom."

Speaking of his love for the film, Burton added, "Gus wants to be a director. He studies this movie for its soundtrack and artistry and that very specific @bazluhrmann trademark of extravagance and heartbreak. He takes the story of Elvis so seriously. I love how he analyzes all of it."

Last fall, Gus made his acting debut on The Walking Dead as a young walker, making him the third member of the family to appear on the AMC series.

Ahead of the episode, titled "Out of the Ashes," Jeffrey Dean Morgan shared a sweet post on Instagram in honor of his son, which featured photos of Gus in his full zombie makeup.

"My dude. Me, @hilarieburton and George THATS MY BOY!! We are super proud of Gusy Dean," Morgan wrote. "Thanks to @amcthewalkingdead and @gnicotero for making a dream come true… a damn hoot! Xxjd"
