Heidi Klum Reveals Son Johan, 17, Might Go to College in New York: 'Very Much Into the Arts and Making Clothes’ (Exclusive)

Heidi Klum's younger son might be following in her fashionable footsteps.

Speaking with PEOPLE at the grand opening of the USA's first CRAZY PIZZA NYC, which opens to the public on Nov. 6, the supermodel, 51, revealed that her son Johan, 17, has been touring colleges as he's set to graduate from high school in May. The mother-son duo even toured a school in New York City this past week, which Klum says plays to the teenager's artistic interests.

"Today, we actually toured Parsons [School of Design] for my second son, Johan," Klum tells PEOPLE at the event. "Johan is very much into the arts and making clothes. So today we toured Parsons."

Klum shares her four kids with ex-husband Seal — Leni, 20, Henry, 19, Johan and Lou, 15.

Last June, the former Project Runway host shared sweet clips on Instagram of her son Henry’s high school graduation as she attended with her husband Tom Kaulitz.

“CONGRATULATIONS HENRY. We are all sooo proud of you ❤️,” Klum wrote in the caption. “You did it my beautiful boy. College here we come 🥳🎉SHINE BRIGHT ❤️.”

Henry, dressed in a graduation gown and cap, was seen in the first video collecting his high school diploma onstage as loud cheers from Klum and others were heard in the assembly hall. After posing for a photo, Henry walked offstage and past Klum, smiling as she shouted, “Yes Henry — woohoo!”

On a January episode of Call Her Daddy, the German model chatted with host Alex Cooper about visiting nude beaches, adding that she tries to extend that free mentality when she's at home.

"I mean, I try to be like that with my kids. Obviously, when you know, no one is there. I’m in my garden also, you know, I’m topless," Klum said. "And they will come, like, ‘You know, my friend is coming over mom, put your top on.’ And I’m like, ‘When have I ever not had a top on when your friend was coming over? Of course I will.’"

"But they always make sure. ‘Mom, just a little warning what’s going to happen here.’ And I’m like, ‘Don’t worry.’ I also don’t want to flash anyone just to flash someone. I just don’t love tan lines."
