Everything you need to know about viral dancing star Gianluca Vacchi

Gianluca Vacchi has taken the world by storm since dancing his way into the spotlight in a now-viral video with his model wife Giorgia Gabriele. But his instant popularity begs a question: just who exactly is Zac Efron's pal? When he's not riding horses shirtless with the High School Musical alum, the Italian tycoon, 48, heads up the manufacturing company SEA Società Europea Autocaravan and shares his luxurious adventures on Instagram.

From his adrenaline-seeking ways to his love of pajamas, here is everything you need to know about the eccentric businessman and his 'GV Lifestyle.'

1. He's best friends with Zac Efron
The actor lived la dolce vita with Gianluca back in 2014 while the duo vacationed in Italy. The pair enjoyed shirtless horseback rides on the beach, danced on tables to Jason Derulo's "Wiggle" and showed off their synchronized diving skills from glamorous yacht. If that's not a bromance then we don't know what is!

At the time, Zac professed his adoration for the businessman on Instagram, sharing a solo shot of Gianluca with a caption that read: "To my friend @gianlucavacchi – the real life 'most interesting man in the world', never above you, never below – always by your side. Luv and respect.'"

2. He's a lifestyle guru
When you've branded your lifestyle with its own personal name, you know you're doing something right! As evidenced by his social media, Gianluca lives a life of which many dream, lounging on lavish yachts, riding a Harley Davidson and traveling via private jet with his Hermes luggage in tow.

He's also not afraid of getting his fine Italian threads wet when it comes to riding a jet ski at the beach. Attached to a video of him playing with the sea-faring toy, he wrote, "In life it doesn't matter what you drive, is how you drive it that makes the difference. Enjoy."

3. He loves his pajamas
While he's rolling in the dough, Gianluca can appreciate the simple things in life - like a pair of comfortable loungewear. The businessman has shared a number of photos hanging around his pool deck in his printed pajama shirts and trousers. On one occasion he noted, "Always pajamas to go on the boat or on the beach."

4. He's an adrenaline junkie
When it comes to his lifestyle, the Internet star likes to live on the wild side. The action man has taken riding his motorcycle to new heights, standing on top of his Harley Davidson's seat — while wearing pajamas, naturally — as the bike was still in motion, cruising down a curved hillside.

Gianluca's daredevil ways have also played out on the high seas with his " crazy sailing" – hanging off a boat's boom. Apart from his adventurous activities above sea level, the Italian tycoon has also taken his intrepid antics below the surface with underwater cycling in a pool.

5. He can dance!
No surprise since his impressive moves are what propelled him into the spotlight. Whether he's doing La Samba in a tuxedo by a pool or shaking it in a swimsuit to Pitbull's "Echa Pa'lla (Maños Pa' Arriba)," this businessman lets his fancy footwork do all the talking.
