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.
