Julianne Hough's red-hot micro bikini steals the show during sun-drenched Italian vacation

Another day, another sun-drenched vacation for Julianne Hough who is currently living the dream in Italy. 

The Dancing With The Stars host must have a wardrobe full of bikinis and swimsuits as every getaway seems to come with a fresh set of swimwear. 

Julianne posted a series of envy-inducing snaps in which she and her female friends were swimming in crystal-clear waters, leaping off cliffs, and lounging on yachts. 

In one particularly striking image, Julianne rocked a tiny red bikini and laid back on the luxury vessel looking every inch a model.

Julianne manages to maintain her very toned, dancer's physique with a consistent blend of pilates, yoga, weight training, and dance-based workouts.

But she's been forced to defend her slim appearance in the past when fans voiced concern over her slender figure and said they were "concerned".

"I don't usually address comments like this but I'm going to say a few things," she said in a statement on Instagram at the time. 

Julianne confirmed she has "never been healthier," and continued: "I was full of inflammation in my 20s and had a marker for an autoimmune that I addressed and committed to over a year and a half ago."

She added: "I’ve frozen my eggs over the last few years which also shifts the body fluctuation. I've never been healthier or happier from the inside out. Grief, loss. Sadness and fear also get stored in the body and we hold on to that in different ways. I made it a huge priority to accept, express, process, and release a lot of emotions over the years."

Julianne insisted she was going to enjoy and "have fun with life," and it looks like she's living by her words.
