Glen Powell and Michelle Randolph Pack on PDA in NYC

Glen Powell and Michelle Randolph are smoochin' in New York City ... and not exactly trying to hide it.

We got photos of the pair out Saturday as they're seen showing some serious PDA while out in the Big Apple ... including multiple moments of hand-holding and a kiss that locked in the romantic outing.

The two appear relaxed as they walk through the city streets together, sticking close, and keeping cozy pretty much the whole time they’re out.

At one point, Glen and Michelle are snapped holding hands while navigating the NYC crowd, before later leaning in for a kiss that leaves little room for interpretation about their vibe.

Both kept things casual in their street style looks, blending into the busy city scene -- though the affection between them definitely stood out more than anything else.

As we previously reported ... The two sparked romance rumors back in the fall after being spotted dancing together in Glen's hometown of Austin, Texas. Since then, they've been gallivanting around and cementing themselves as one of Hollywood's newest it-couples.
