P.K. Subban Hits Knicks Game W/ Mystery Woman 10 Months After Vonn Split

P.K. Subban appears to be firmly back in the dating world after ending his engagement with Lindsey Vonn ... 'cause he was spotted out with a mystery woman at the Knicks game Wednesday night.

The NHL star cruised to Madison Square Garden with the woman by his side ... and while they never held hands or showed any kind of PDA publicly -- it's clear they showed up and left together.

No word on who the woman is or how the two met ... but it's the first time P.K. has been linked to a woman since his split with Vonn back in Dec. 2020.

The high-profile couple broke things off after dating for about 2 years ... with Vonn saying at the time, "We will always remain friends and love each other immensely."

Vonn has been spotted out in public with businessman Diego Osorio ... though it's unclear if they're an official couple.

Subban, meanwhile, didn't have much to say after watching the Knicks beat the Celtics in a double-overtime thriller on his off night from his Devils team ... only telling a camera guy, "I gotta get home now!"
