No summer blues for this bathing beauty. 

Heidi Klum’s 19-year-old daughter, Leni, is soaking up the end of summer aboard dad Flavio Briatore’s yacht in the South of France — and showing off some sexy swimwear while she’s at it.

On Wednesday, the teen cover girl was spotted jumping into the water while wearing a blue terry two-piece from Frankies Bikinis.

The sold-out style is comprised of a classic triangle top and matching thong bottom, both with orange piping.

Leni rocked the same style on her Instagram Story last summer.

“I think Leni Klum got her mom’s genetics,” one Twitter fan mused of the model.

Heidi broke up with Italian businessman Briatore while pregnant with their daughter in 2004, and after she married Seal in 2005, the “Kiss From a Rose” crooner adopted Leni.

Seal and Heidi split in 2012 and finalized their divorce in 2014, and the “America’s Got Talent” judge wed Tokio Hotel rocker Tom Kaulitz in 2019.

Dior Beauty ambassador Leni appears to be following in her mother’s footsteps; Heidi famously loves a sexy swimwear moment, whether she’s showing off her abs on vacation, getting cheeky in Versace or ditching her bikini top altogether.

Hopefully, Leni remembered to pack her SPF this time around. In July, she showed off a massive sunburn on Instagram following a day of outdoor fun.

“Obviously didn’t use enough sunscreen,” Leni captioned the painful-looking snap.

The Intimissimi campaign star shared a similarly crispy bikini photo of herself looking “a little past sun kissed” a few days earlier, with fans begging her to use sunblock.

Hopefully, Leni has learned her lesson — or at least has some aloe vera on hand.
