The Hoff is back on the beach!

David Hasselhoff is making his return to Baywatch, and two people who can't get enough of it are the stars of the upcoming reboot, Zac Efron and Dwayne 'The Rock' Johnson, who absolutely gushed over the 63-year-old actor re-joining the lifeguard crew.

"Getting schooled. Wisdom from the original #Baywatch badass himself @davidhasselhoff," Efron shared on Instagram. "What an honor to meet #TheHOFF."

Meanwhile, Johnson shared a shirtless snap with "the OG himself," writing, "In the 80's he drove the coolest car on the planet. In the 90's he dominated slo-mo running on the beach with the most successful TV show of all time. And today he's simply the f'n man."

"Great dude with a great sense of humor," Johnson continued. "AND he trained his a** off for our movie."

That much is evident! Hasselhoff looks as hunky as ever as the cast continues to build anticipation for the film's May 2017 release.

ET was the first to visit the set last month, where Efron and Johnson couldn't help but admire each other's physique.
