Four-time Super Bowl champion Rob Gronkowski celebrated his birthday in style this week, stepping out to support his longtime girlfriend, Camille Kostek, at the 2026 Sports Illustrated Swimsuit Issue launch party in New York City. While walking the red carpet at the Hard Rock Hotel, the NFL legend was treated to a spontaneous “Happy Birthday” serenade that quickly went viral, thanks to an unforgettable, hilarious cameo from comedian and cover model Tiffany Haddish.
A Star-Studded Celebration
The 2026 SI Swimsuit red carpet was already buzzing with major star power, but the energy completely shifted when Gronkowski arrived alongside Kostek. Dressed in a sharp, multidimensional jacket perfectly coordinated with Kostek’s plunging purple gown, Gronkowski was visibly thrilled to celebrate his big day at one of the fashion world’s biggest annual events. As photographers snapped pictures, the press line broke out into a chorus of “Happy Birthday” for the beloved former tight end, prompting huge smiles from the couple.
Tiffany Haddish Crashes the Party
The absolute highlight of the viral moment came courtesy of 2026 SI Swimsuit cover star Tiffany Haddish. Never one to miss a comedic beat, Haddish loudly chimed into the serenade from down the red carpet, bringing her signature boisterous energy to Gronk’s special day. The hilarious shoutout perfectly captured the fun, lively vibe of the exclusive VIP launch party, which later featured a surprise performance by Fetty Wap to close out the night.
