Rajon Rondo didn’t have to wait for the NBA season to pursue another ring … ’cause the 2-time champ just popped the big question to his girlfriend — and she said “yes!!!”

The 4-time All-Star got down on one knee and asked for his partner Latoia Fitzgerald’s hand in marriage Thursday night … and it was one of the biggest nights of her life in more than one way, as she was also hosting a huge NYFW event for her clothing brand, “Lionne.”

Right as the show ended, Rondo hopped up on the runway as Latoia’s back was turned … and when she turned around and saw him, he found his opportunity to propose.

Rondo’s move seemed to be a real shocker to Latoia and the guests, who crowded around the couple and cheered as she accepted.

Rondo wasn’t the only household name in the building, either … Draya Michelle, Fivio Foreign and Flo Milli were among other celebs in attendance.

Rondo and Latoia have been dating for a while. She’s a fashion designer from Philly … and, now she’ll be taking on a whole new title — last name, that is!
