Leonie Hanne is adding a new stamp in her passport … because she’s on a getaway in Asia, and she’s bringing the heat.

The German fashion model is visiting Thailand for an island adventure … her vacation — and her body — looks like a dream.

Leonie is showing off the goods in some sexy bikinis … busting out the swimwear for some boat rides and poolside relaxation.

All of Thailand’s greatest hits are on display here … monkeys, jungles, infinity pools, islands … and Leonie’s soaking it all while looking amazing.

Leonie’s worked with huge brands like Dior, Cartier, Louis Vuitton, Givenchy and Tommy Hilfiger … and she’s making Yao Noi Island her own personal runway.
