Julianne Hough isn't letting internet haters get her down.

The dancer, 35, who posed topless while enjoying a cruise in Ibiza, received a lot of criticism from followers after she posted a video showing her stretching session in her sauna. 

The Dancing with the Stars alum showcased her toned form donning a brown bikini in the video which she captioned: 'Six Senses Sizzling Sauna Stretches.'

'I definitely was like, "Oh, this looks really good. I'm going to put a fun, sexy song to it,'' she told People, explaining it was a spur of the moment decision to record the clip. 

'And sure enough, I laughed so hard, I got more views on that post than something else that I'm talking about, like my book, for instance,' she said.

Some of the statements included 'This.is.just WEIRD!!!' and 'Eat something...you're too skinny.'

'And we need to see you doing this why???' questioned another. 

Others were supportive of the Grease Live! star.

'She’s in great shape and I guarantee you she works for that body with hard work, diet, and discipline,' wrote a fan.

'You don’t need my validation, but you look wonderful. a picture of dancers life to be hours and hours of practice to get in peak physical shape. Great job,' maintained another. 

Commenting on the reactions to the June 7 post, Hough explained the caption was a joke, but she was fascinated by society's double standard when it comes to making remarks about women's bodies. 

'It's like you can see men with their shirt off constantly and they're in a sauna or a cold plunge or whatever, and the minute a woman does it in a bikini, it somehow changes the perspective, which is totally fine. I get it,' she said.

The Dolly Parton's Heartstrings actress said she uses the sauna to keep her muscles loose.

 'I'm a 35-year-old woman who is proud of my body, and I'm okay to post that,' she said.

Hough's latest project is new book, Everything We Never Knew: A Novel, co-written with Ellen Goodlett. 

The supernatural thriller is her first foray into the world of fiction.

Everything We Never Knew was scheduled to be store bookshelves August 13.
