The model is ringing in 2019 with some sexy black lingerie and a bottle of bubbly, giving us a shower routine for the ages during this shoot with Chris Applebaum ... trust us, you're gonna wish Hallie was your New Year's kiss!

Ya gotta see what happens when Hallie starts popping bottles ... safe to say sparkling wine flows just fine where the sun don't shine!

The fun doesn't stop when the bottle is empty ... because after Hallie dries off, she slips into a bra and panties and dances around as confetti rains down.

Yeah, this beats the hell outta Times Square.
