Jennifer Lopez brought some serious heat to St. Barts … strolling down the sandy white beach in a teeny white bikini top.

The multi-talented star paraded her toned bod while catching some rays … completing the vacation look in a large straw hat, shades, and a pink towel wrapped around her hips.

With headphones plugged in, J Lo was in complete R&R mode … clearly making the most of her festive Caribbean getaway following a busy year.

Things will kick off again in the New Year for Jen — especially with the February release of her new doc, “This Is Me … Now.”

The film will focus on her rekindled romance with Ben Affleck and their 2022 nuptials … so looks like the husband/wife duo will be hot on the promo trail soon.

For now, J Lo is recharging in an island paradise … and blessing us with some hot shots.
