Topless Heidi Klum Packs on PDA With Tom Kaulitz on St. Barts Beach

Heidi Klum and her husband Tom Kaulitz had yet another titillating beach afternoon this week ... they were all over each other while the supermodel soaked up the sun topless. Keep reading for some trivia about the blonde bombshell below!

The married couple were at Saline Beach in St. Barts on Monday ... and were snapped packing on plenty of PDA while HK stunned with her rocking bod.

As you can see from the snaps ... the 52-year-old Heidi was not in a modest mood as she strutted around the sand nearly nude.

Of course ... HK showing off the goods is not a one-off -- she's been snapped a few times recently on the beach sans bikini top with her German guitarist husband. He's topless, too ... but who cares!

Hey, when you got it, flaunt it!
