Julianne Hough Bikini Pictures

Ashley Tisdale and Julianne Hough slipped into another set of bikinis and hit the beach in Miami yesterday. The girls are hanging out in the Florida city where Julianne has been working on Rock of Ages, and Ashley is visiting her boyfriend Scott Speer on the set of Step Up 4. Ashley tweeted a big thanks to Julianne for including her on "all the fun stuff" while Scott is off working. Julianne and Ashley had a bikini jet-ski adventure over the weekend with Derek Hough along as well. Some of Julianne's Rock of Ages costars, like Tom Cruise and Alec Baldwin, have already finished filming on the movie, but she and director Adam Shankman are still toiling away in paradise. The location has certainly given Julianne an opportunity to perfect her tan, and both she and Ashley are going strong in our celebrity bikini bracket — make your picks for a chance to win $1,000 to J.Crew!

Ashley Tisdale and Julianne Hough spent their Saturday afternoon out riding jet skis in Miami. Julianne's brother Derek was along for the fun, and he went shirtless while wearing just his swimsuit. It seems Julianne has been able to enjoy many hours away from the set during her stay in Florida working on Rock of Ages — there's been plenty of Julianne Hough bikini time between her visits to the pool and beach! Ashley has likewise been getting good use out of her two-piece collection this Summer, including during a getaway to Mexico and her birthday celebrations in Las Vegas. Ashley's trip to Florida was so that she could see her boyfriend Scott Speer, who's shooting Step Up 4 there. She followed up the day on the water by meeting up with Scott for an Italian dinner. Julianne, meanwhile, was busy yesterday checking out a screening of her other new movie, Footloose. The dance film is out in October, and she got her brother and Rock of Ages buddies like Adam Shankman and Diego Boneta together to check out an advance cut.

Julianne Hough was in a bikini yesterday to go for a swim at her Miami hotel! She cooled off in the water after a stroll on the sand with her mom, Marianne, and her shirtless Rock of Ages costar Diego Boneta. Diego was still by her side to splash with other friends, as he and Julianne enjoyed the afternoon off from movie making. Diego's no stranger to seeing her in a two piece, after he had some Julianne Hough bikini time on set in late May. Julianne's real-life leading man is Ryan Seacrest, and he was in Miami just over a week ago to see her. Ryan couldn't be there this weekend, because he was off at producer Ryan Kavanaugh's Capri wedding. Last night, though, was all about family for Julianne, since she shared a photo of her and Marianne making dinner together.

Julianne Hough was in a high-cut purple bikini yesterday to shoot Rock of Ages in Miami with her costar Diego Boneta. She's made sure to fit regular workouts into her shooting schedule, and she showed off all her hard work in the skimpy two-piece. She and Diego seemed to be having a blast on set, and he tweeted after they wrapped for the day that their stint in the water was a great way to start the awesome adventure of filming. Julianne, meanwhile, wrote about how their director, Adam Shankman, was occupied by clearing the beach of seaweed in order to have the scene look as tidy as possible. There was more Hough family fun in store, since Julianne's sister Marabeth was on hand, too. Lounging in a swimsuit seems to also be one of Julianne's favorite things to do in her downtime. There was more Julianne Hough bikini last week when she hung out by her hotel pool during a day off from the set.

Julianne Hough took a break from rehearsal and slipped into a bikini today to chill poolside at her Miami hotel. She hit the beach later and met up with her older sister Sharee and her newborn nephew Quaid, then changed into workout gear for a solo bike ride along the shore. Julianne's stay in Florida has allowed her to hang out with family, friends, and her treasured pups, Harley and Lexi, who were her companions last night for a walk in the city. She's been hard at work too, hitting the gym and practicing choreography for Rock of Ages. Her boyfriend, Ryan Seacrest, is back in LA, meanwhile, and had the difficult task of sending home another contestant last night on American Idol. Ryan and the American Idol judges said goodbye to third-place finalist Haley Reinhart, leaving Scotty McCreery and Lauren Alaina left to battle it out for the title.

Julianne Hough busted out a hot pink bikini for a trip to the beach in Miami yesterday. She was with friends for the fun day in the sun, which included splashing in the ocean and relaxing in a lounge chair. Julianne's boyfriend, Ryan Seacrest, didn't join her in the sand, though he was by her side at last week's Met Gala. The couple hit the red carpet in Burberry before parting ways to get back to work. Julianne's getting started on Rock of Ages with wardrobe fittings and studio time in Florida while Ryan returned to his daily routine in LA. Julianne does have the company of her pups though, and she brought Harley and Lexi to a dog park this morning.
