Heidi Klum’s daughter Leni, 19, wears green bikini while in France

She’s got them green with envy.

Heidi Klum’s 19-year-old daughter, Leni Klum, is continuing to show off her busty physique in sexy swimwear while vacationing in the South of France.

In photos exclusively obtained by Page Six Saturday, the teen was spotted on a luxury yacht — owned by her dad, Italian businessman Flavio Briatore — with her boyfriend, Aris Rachevsky, near Cannes on Friday.

For the sunny outing, Leni wore a strappy green thong bikini and pair of sunglasses.

At one point, the model and her beau shared a kiss as they laid out to catch some sun rays on the pricey vessel.

Leni was also spotted rinsing herself off aboard the yacht and taking pictures of her friends.

Earlier this week, Leni was spotted jumping into the water with friends off her dad’s yacht while wearing a blue terry two-piece from Frankies Bikinis.

The sold-out style featured a classic triangle top and matching thong bottom, which both have orange piping.

Leni seems to be following in her mother’s footsteps, as the German model famously loves to show off her toned body in sexy swimwear.

Klum also is known to show off her abs on vacation, even ditching her bikini top during an Italian trip with her husband, Tom Kaulitz.

Leni, who is the eldest daughter of Klum and Briatore, was also adopted by singer Seal — who was married to the supermodel from 2005 to 2014 — in 2009.

And though she comes from a famous lineage, she doesn’t want anyone to doubt her work.

“It’s just a fact. My parents are famous,” the Dior Beauty ambassador told People in October, referring to the nepo baby debate. “I did get help starting off, and I know that people would dream to start off with what I had.

“I’m so grateful that I’ve been able to take what was gifted to me by my mom. But I am doing the work and putting in the time.”Now I’m working on my own, traveling alone, going to school. My mom and I just have the same love for the same thing.”
