Julianne Hough All Smiles as She Shows Off Her Chiseled Abs in Steamy 35th Birthday Post: 'The Heat Is On'

Happy Birthday, Julianne Hough!

On Wednesday, July 19, the Safe Haven actress posted a gorgeous bikini picture one day before she turned 35.

In the steamy snap, Hough sat on her knees while on top of a paddleboard in Austria. The blonde beauty wore a small red bikini as she showed off her chiseled abs to the camera. Additionally, she had on a large, brimmed straw hat.

"Paddleboard and good vibes only 🌊," she captioned the photo of herself on the water.

In response, fans gushed over the celebratory Instagram upload.

"And maybe a little SPF 😉," one person suggested, while another said, "Wait this makes me soooo happy!!! Austria looks good on you."

"The Heat is On!!! You're Awesome, Jules!!!" a third person penned, while a fourth wrote, "Hopefully you know how stunningly amazing you look."

Just a few hours after her social media upload, on Thursday, July 20, Hough began to re-post some birthday wishes to her Instagram Story.

The star received a plethora of birthday wishes, including one from famous friend Nina Dobrev.

The loving shout-out included a picture of the pair as the Vampire Diaries alum stuck out her tongue and crossed her eyes, while Hough also showed her tongue to the camera. Dobrev also shared a polaroid of herself, boyfriend Shaun White and Hough, along with a "Happy Birthday" sticker underneath.

As OK! previously reported, the Footloose star has a lot to look forward to in her 35th year as she was hired to replace Tyra Banks as the co-host of Dancing With the Stars.

"It is such an honor to be rejoining Dancing With the Stars as co-host. The show holds such a special place in my heart from the many years and different roles I have had the privilege of being a part of," Hough revealed on March 20, just a few days after Banks announced it was "time" for her to leave the show.
