Alexandra Daddario shows off pert derriere and ample cleavage during pH๏τo shoot with The Rock on Miami set of Baywatch

She was spotted getting flirty with Zac Efron on Saturday.

But Alexandra Daddario gave her full attention to The Rock during a pH๏τo shoot on the Miami set of Baywatch on Monday.        

The 29-year-old actress and model showed off her pert derriere and ample cleavage in a blue and red ʙικιɴι.

She flashed several smouldering poses for the lens in a Sєxy two-piece swimsuit while getting playful with her hunky costar.

Alexandra – who plays Summer Quinn, cast in the original TV series by Nicole Eggert – left little to the imagination in the tiny ʙικιɴι bottoms.

Her long, bronzed legs were on full display as she ran her fingers through her silky brunette tresses which fell in loose waves.

Clearly not shy about flaunting her incredible figure, the Layover star wore the revealing top with plunging neckline.

The showy swimwear featured a gold zipper detail in the center and the word ‘lifeguard’ emblazoned in white on the back.

Baywatch is being produced by Dwayne ‘The Rock’ Johnson, who also plays the lead lifeguard Mitch Buchannon.

He wore a coordinating two-tone costume and hammed it up for the camera with his former San Andreas costar.

Once their pH๏τo-taking was complete, Alexandra and The Rock – along with Efron – were spotted doing interviews with MTV.

But it was a few days earlier when things really steamed up on set as Alexandra and Zac shared some playful flirtations between takes.
