David Hasselhoff confirmed for Baywatch movie

Just when you thought the Baywatch movie cast was finalized, Dwayne "The Rock" Johnson dropped a major surprise Wednesday night on Instagram.

Bust out the red swim trunks David Hasselhoff because you're heading to the beach.

"Pleasure to officially welcome the original #BAYWATCH gangsta himself David Hasselhoff to our movie!" The Rock shared on social media with a video of himself Facetiming with his upcoming co-star. "#BAYWATCH is the most successful TV show of all time and from the day we announced we were turning it into a movie, ‘The Hoff' has been our greatest supporter. Especially once he knew our RATED R movie was going to be a combination of AVENGERS meets ANCHORMAN."

He continued, "Hoff's a cool dude who's down to have fun and here's the best part…He's been training his ass off and gotten in the best shape he's been in in years!"

For those who needed proof that the actor was ready for the big-screen project, David appeared in the Instagram video where he showed just how confident he was.

"Come on, man. Rocking the Hoff," he explained. "I was born ready."

With filming well underway in Boca Raton, Fla., E! News has learned that Zac Efron, model Kelly Rohrbach and Priyanka Chopra have all signed up for the highly anticipated flick. And yes, first images from the set show a very good-looking crew.

"Zac's ad-libbed responses were brilliant! Talented and great dude," The Rock shared on Instagram. "World get ready to have some fun, 'cause the beach will never be the same again."

As for what we can expect once the finished project hits theatres in 2017, let's just say it's going to get hot! 

"Edgy, raunchy and hopefully, funny as all hell," The Rock added in a separate post. "Cue slo mo running on the beach... #WhoNeedsMouthToMouth #RedShortsBeHugginABrotha."
