Rob Gronkowski Is the MVP of Valentine’s Day With These Romantic Plans

By September 2015, the two made their relationship Instagram official, with Kostek sharing a black-and-white photo of her and Gronk alongside the caption, “friday night date night.”

Since then, they’ve been each other’s biggest support systems, both on and off the field. 

“Happy birthday to you my love,” Kostek wrote in a May 2022 Instagram post for her partner’s special day. “Cheers to more life, laughter, love, memories, travel, and dancing together.”
