Of course Baywatch is being ballsy.

The Rock has released a poster for the upcoming Baywatch movie reboot and it's in a very X-rated shape.

The action hero - who stars in and produced the silver screen version - released the poster on social media today, which features his name and co-star Zac Efron's plastered on beach balls, with a surf lifesaving board strategically positioned behind them to make a shape resembling the male appendage.

It appeared under the heading, "Get your guard on".

An alternative version of the poster features the motto, "Lifesaving takes a pair".

"Because the climate is right for a good ol' RATED R rescue can and beach balls shaped in the form of a penis and testicles joke," The Rock wrote under the image.

Baywatch is out in Australia on June 1.
