John’s rep, Zach Rosenfield, told Page Six the FUBU founder and CEO proposed at the start of lunch: “It was the last day of shooting for the season, and he had asked her to come to set.”

John, 47, went big on the bling for his lady. He told Us Weekly that he custom-designed a 9.5-carat emerald-cut diamond ring for his new fianceé.

“Everyone was very excited and happy for him,” his rep said. “There were streamers and champagne.”

Co-stars Mark Cuban, Barbara Corcoran, Robert Herjavec, Kevin O’Leary and Lori Greiner were all present for the proposal. The new season premieres Friday.

John will continue the celebrations in New York this weekend as a co-host of the Global Citizen Festival, with performers including Rihanna, Kendrick Lamar, Demi Lovato and Metallica.

Congratulations Damon!
