The former "Quantico" actress shared a tribute to her other half on Monday night as she celebrated the launch of his tequila brand Villa One.
Posting a snap of herself and her spouse at the launch party, Priyanka, 37, wrote: "So proud. When you own your own tequila at 27! @villaone."
However, Nick is actually still 26 - and doesn't turn 27 until his birthday on 16 September.
Many of her followers were quick to point out Priyanka's error, with one writing: "26* for 14 more days."
"Well technically he's 26 until the September 16th," another added, while a third wrote, "Uh isn't he still 26.... just saying."
But Nick either didn't notice or seemed unperturbed by his wife's error, as he commented: "My beautiful forever date."
