The couple were spotted packing on the PDA while cheering on Serena Williams during her quarter final victory at the US Open on Tuesday.
Sweetly holding hands and kissing each other's foreheads, Nick and Priyanka couldn't take their hands off one another. The "Quantico" star was practically blinding spectators flaunting her giant engagement ring while adorably holding tight to her beau.
Priyanka, who brought her mom along as well, showed just how close she is with her soon-to-be in-laws too, sharing adorable moments with Nick's brother, Joe, and his finacée "Game of Thrones" star Sophie Turner.
And although we are awing over Nick and Priyanka's affection during the event, nothing compares to the show Joe and Sophie put on the day before!
The foursome weren't the only stars in the crowd cheering on Serena.
