Heidi Klum sizzles in seriously strappy ʙικιɴι on Instagram: ‘Not sure about these tan lines later’

We’re seeing spots — and not much else.

Heidi Klum modeled a practically microscopic leopard-print ʙικιɴι in a “beach time” Instagram post Tuesday.

In the racy Reel, Klum slinks toward the camera in the strappy swimsuit, which she paired with a delicate gold waist chain, several necklaces and black rimless sunglᴀsses.

“Beach time 😎🏝️🐠… not sure about these tan lines later 👙☀️,” the model, 51, captioned the post.

Klum and husband Tom Kaulitz are currently celebrating their fifth wedding anniversary with a tropical trip.

The former Victoria’s Secret Angel been posting videos and pH๏τos from the couple’s getaway on social media over the past several days, even ditching her swim top for one cheeky clip filmed on the beach.
