One day you’re in and the next you’ve moved out.

Heidi Klum and Seal‘s son Johan Samuel, 18, has headed off to college, with his Project Runway host mom helping him move into his new digs in New York City.

Heidi commemorated the milestone moment by posting a group selfie to Instagram August 19 taken by daughter Leni Klum, 21, in an elevator with her, Johan and another one of her sons Henry Samuel, 19—both of whom she also shares with her ex Seal along with 15-year-old son Lou.

In the family snap, Heidi rocks a red New York Yankees baseball cap, a black E.T. t-shirt and aviator sunglasses, while her kids all rock solid black tops as they’re surrounded by Johan’s stuff that they’re bringing into his new place.

The 52-year-old captioned her post, “College move in day NYC,” along with heart and State of Liberty emojis.

While she hasn’t confirmed where Johan chose to go to college, the supermodel did tease last year where he might be interested in going.

“Today, we actually toured Parsons for my second son, Johan,” Heidi told People of the top design school in October. “Johan is very much into the arts and making clothes.”

She also celebrated his high school graduation at the beginning of the summer.

“CONGRATULATIONS JOHAN,” she captioned an Instagram roundup of content from his commencement in June. “My heart is full of joy and pride.”

Heidi added, “Cheering you on today and every day.”

The model posted a few videos from Johan’s ceremony, including one of her showering him in kisses and another where you could hear her cheering him on as he received his diploma.

Meanwhile, Leni and Henry have followed in their parents’ footsteps in the entertainment business, with Leni having already collaborated with her mother on numerous fashion campaigns together and Henry paving his own path in the modeling world, making his Paris Fashion Week debut back in January.

“So proud of you Henry,” Heidi wrote on Instagram at the time. “Opening the Lena Erziak Haute Couture Show in Paris @henrysamle @lena_erziak.”

And, yes, Seal approves of his son’s career path.

“Seeing him in those photos having such a great time and looking like he was really enjoying the experience,” the singer (real name Seal Samuel) told E! News in February, “that personally is what gave me great happiness.”
