Jack, who is signed by Wilhelmina Models, got his first gig on the runway when he was 16. In January 2018, he walked for Dolce & Gabbana in their Men's Fashion Week show in Milan. The brand also featured a handful of other celebrity kid models, including Pierce Brosnan's son, Paris Brosnan, and Jude Law's son, Rafferty Law.

Jack's dad, who sat in the front row at the show, shared photos of his son on the catwalk on Instagram. "Could not be more proud of my oldest son @jackmarsden walking his first show for @dolcegabana… #proudpapa," he wrote in the caption.

In a July 2017 interview with Wonderwall back when Jack was just "dipping his feet" into the modeling world, James shared how impressed he already was with his son.

"It would have been crazy for me at 16, but nowadays, this is when people start," James said. "But we're supporting him. I didn't know what the h*** I wanted to do at that age. I think he's just trying to figure it out. You don't think 'career' at 16, but if he wants to learn about it, great."

Jack is also a musician. 

In July 2020, Jack, who also goes by the name Jack Holden, released his first album, To the planes. Last week, the musician announced on Instagram that he'll be releasing his next single, "Kiss," on June 15.

While he only recently started releasing his work, he's had an interest in music ever since he was a kid. In his official bio on Wilhelmina Models, he noted that he started playing the drums when he was only five and has grown as a musician since. Jack also credited his musically inclined dad, who's sung in movies including Enchanted and Hairspray, for helping him foster his passion.

"My special talent when it comes to music is that I'm able to teach myself the basics of an instrument, all by ear," he explained. "But if it wasn't for my dad, I wouldn't have known how to get myself started. Shoutout to dad!"

Jack also added that outside of music, he enjoys video games and spending time with his friends, just like any other "teen would be into."

James has said that being a dad is one of the biggest achievements in his life, though his projects require him to be apart from his kids sometimes.

"It's one of the things I'm most proud of," he told ABC News in 2014. "Work is difficult because you've got to spend time away from home, but it's always nice to come back and not have to do anything, just spend time with them."
