BLACKPINK's LISA heard a groundhog predicted six more weeks of winter in the United States and she decided to take full advantage ... slipping into a bikini for a sexy photo shoot in the snow.

The Thai K-pop mega star ventured out into the frozen tundra in her Nike x NOCTA x Chrome Hearts puffer jacket and matching pants and unzipped her coat to reveal her slim figure in a skimpy bikini top.

Frankly, we're surprised the snow around LISA isn't melting here ... that's how HOT she is!!!

LISA recently inked a deal with the Swoosh and starred in an ad for NikeSKIMS ... so she's very hot right now in the fashion world, too.
