The 22-year-old dancer showed off her impressive assets as she frolicked in the ocean with co-star Diego Boneta on the set of their new film, Rock Of Ages.
The Eighties-style skimpy swimsuit accentuated the beautiful blonde's well-honed body, which she has been perfecting with intense work-outs over the last two weeks.

This morning Julianne hit the Miami set of the film for the first time.

And judging by her outfits so far, it appears that Julianne has every opportunity to show the result of her recent daily hardcore workouts outdoors with a trainer.
Both her and Diego wore matching denim shorts with retro looking sunglasses this morning.
The former Dancing With The Stars pro also wore her long blonde hair pulled into a high side pony tail controlled with a scrunchy.

The on-screen couple held hands and even shared an intimate kiss as the camera's rolled, with Diego placing his arm affectionately round his on-screen love.
Earlier in the day Julianne arrived on the Miami Beach set dressed casually in a tiny denim mini skirt and bright red top which she paired with black boots.
Rock Of Ages is a remake of the 80's classic film which also stars Tom Cruise, Malin Akerman and Russell Brand.
