The 29-year-old Sports Illustrated Swimsuit model took to Instagram on Sunday to post several photos of herself posing on the beach.
In the pics, Kostek is seen wearing a two-piece paired with denim jeans which aren’t pulled up all the way.
The sizzling photoshoot appears to be a part of Kostek’s upcoming swim collection campaign, which is set to be released on May 3.
Earlier this month, Kostek shared a video montage that featured her rocking a similar outfit.
“ONE MONTH until the drop and then I can share this entire Camille Collection x @swimsuitsforall !!! Until then here’s a sneaky sneaky peek,” she wrote alongside the post.
Kostek also recently appeared alongside her boyfriend, NFL tight end Rob Gronkowski, on the “10 Questions with Kyle Brandt” podcast, where fans got to see the longtime couple’s chemistry in action when they were answering personal questions and trivia.
