Rob Gronkowski stars in girlfriend Camille Kostek’s teaser for supermodel's new swimsuit line La Porte [In Pics]

Supermodel Camille Kostek is making a move into fashion entrepreneurship, and she’s bringing longtime partner Rob Gronkowski along for the ride.

The retired NFL tight end made a surprise appearance in a new teaser video promoting Kostek’s swimwear line, La Porte, set to drop on Friday.

The teaser, shared by the brand on Instagram on Tuesday, gives fans a sun-soaked glimpse into the couple’s dynamic. Kostek, 33, models a variety of sleek designs from the upcoming collection, while Gronkowski, 36, complements the aesthetic in relaxed swim shorts.

Early access to the line begins June 12 through the brand’s official website, according to the caption of the Instagram post.

For over a decade, Kostek and Gronkowski have built a public image rooted in shared experiences from game days to red carpets. Their romance began in 2013 when she was a Patriots cheerleader.

While La Porte marks a major step into fashion for Camille Kostek, it’s hardly her first business-facing endeavor this year. She’s secured partnerships with consumer brands like Sally Hansen and Durex.

Kostek gained steam during Miami Swim Week, where she appeared in Sports Illustrated’s exclusive beach club alongside notable names like Alix Earle and Olympian Ilona Maher.

In a June 6 post from the event, she paired a cherry-print skirt with a cropped sweater that sparked praise from fellow models and celebrities alike.

The couple’s charisma often lends itself to interesting anecdotes. During Sports Illustrated’s launch party in May, the model-turned-entrepreneur revealed that a snowmobile ride in Utah ended in an unexpected tumble.

"You flipped us," she teased Rob Gronkowski during a live interview.

"It was so much snow, Gronkowski said, "so we kind of sunk and then... We just fell off."

Camille Kostek called the moment "crazy," while Rob Gronkowski insisted it wasn't dangerous. Though snowmobiles might be off the table, she confirmed jetskiing remains a regular adventure.

Kostek’s recent Sports Illustrated Swimsuit content in May featured a lingerie shoot, which she shared on Instagram. While her Switzerland shoot had a winter aesthetic and vibe, warmer conditions were needed for her swimwear sessions.
