Heidi Klum‘s year of freeing the nipple keeps rolling on … because she hit the beach once again without a bikini top.

The supermodel and her husband Tom Kaulitz were spotted walking down to the ocean on St. Barts earlier this week … both of their bare chests puffed out.

The two laughed and smiled while wading into the water together … holding hands and later locking lips.

The lovebirds later retreated to the beach where Heidi threw on a yellow top, obscuring the view of her chest … though her long legs certainly still drew some eyes.

Heidi’s topless form might be old news to TMZ loyalists at this point … because this ain’t the first time we’ve shared half-naked pics of this star with you in recent weeks.

Remember, Heidi ended her year by stripping off her top and diving into the water on a couple of separate occasions … at one point sipping on a drink in the ocean and seemingly unbothered to drop her top in front of her and Tom’s friends.

We later saw her in a baby blue bikini, so we thought she’d gotten tired of the public frenzy surrounding her nudity … then, earlier this week, we saw her splashing around the water and packing on the PDA with Tom sans top once more.
