Karlie Kloss celebrates her birthday by jumping off a yacht: 'Kissing 26 goodbye'

Supermodel Karlie Kloss turned 27 on Saturday, and she's celebrating exactly as she should: on a yacht in the Mediterranean.

"Kissing 26 goodbye," Kloss captioned an Instagram Boomerang video of herself jumping backward off a boat on Friday.

The post attracted well wishes from many of Kloss' famous friends, including Reese Witherspoon, Gwyneth Paltrow, Priyanka Chopra, and Cindy Crawford.

"You’ve achieved so much already," Elle McPherson wrote under Kloss’ photo. "Inspiring role model and savvy smart business woman with a huge heart - Beauty on the outside matching beauty on the inside. And you’re TALLER than me. Looking foreword to watching you shine even brighter (if possible) next year."

On Friday, Kloss also posted a message to her “birthday twin” model Jourdan Dunn, who turned 29 on the same day.

“Happy (early) birthday to my Aug 3rd bday twin, my best friend and soul sister!” Kloss wrote. “Luv you Jour. Cheers to many many more years of jourlie adventures.”

Also on Friday, journalist Yashar Ali tweeted a photo of Kloss engaging in pre-birthday celebrations with husband Joshua Kushner on music mogul David Geffen's yacht Rising Sun (reportedly worth $590 million). On board were Oprah, Gayle King, Discovery Communications CEO David Zaslav, former Goldman Sachs CEO Lloyd Blankfein.

This elite crowd appears to be sailing to Sicily for the annual Google Camp, according to Forbes. Some of the world's most powerful people gather at the summit, held at the Verdura Resort in the town of Sciacca, to discuss ideas in technology, fashion, entertainment, human rights, education, and the environment.

Though the event has a secret guest list, Katy Perry, Orlando Bloom, Priyanka Chopra, Barack Obama, Leonardo DiCaprio, and Prince Harry are reportedly attending.
