“Holiday Giveaway.✨ There is nothing like a classic pair of diamond studs, so I’m giving away these beautiful Brilliant Earth 2 carat 4-prong certified lab diamond stud earrings to a lucky winner!” Kostek wrote.

Brilliant Earth is a U.S. jewelry company known for selling diamonds and gemstones. The company was founded in August 2005 by Beth Gerstein and Eric Grossberg and is based in San Francisco.

Kostek had an emotional message and mentioned Patriots owner Robert Kraft on Nov. 12. Gronkowski returned to Gillette Stadium to sign a one-day contract with New England. It allowed him to retire with the franchise he won three Super Bowls with.

Kraft welcomed Gronkowski back and praised him for his nine seasons with the team. Kostek talked about how the Patriots played a big role in bringing their lives together.

“Your team brought us together,” Kostek said during the press conference. “If we both didn’t make our Patriots teams, we wouldn’t have met. My life would’ve been different if I didn’t make the cheer team and you didn’t make this organization.”

The couple’s love story started during their time with the Patriots. They first met at a Goodwill charity event in November 2013. The tight end was already an NFL star at the time, while Kostek was a Patriots cheerleader.

The couple went public with their relationship in September 2015 after Kostek left the cheerleading squad.
