The X Factor judge and former Pussycat Doll showed off her impressive yoga moves on her Instagram page, captioning the snaps with what she's been up to back in Hawaii.

"Beautiful hike this morning!" she posted next to this picture of her by some rockpools.

"Yoga gone bad, lol!" she admitted with another photo.

On a third image, this time of her lounging on the golden sand, she wrote: "#Shaka #hangloose Sending nothing but sweet #aloha & #blessings to everyone! #HAWAII."

The 35-year-old last year spilled the beans on what helps her stay so trim on the beach.

And it turns out the secret is not in some faddy diet, weird fitness kick or peculiar celeb health trend – instead, it's all about enjoying the things she likes in smaller portions.

"My new motto is: 'Stay active, eat everything in moderation and stop being so tough on myself’," the 35-year-old has said in the past.

"I work out a lot. I jog a lot. I keep very active and you've just got to find the balance. I don't believe in being too skinny or unhealthy. I believe in being healthy and having a healthy appetite, like I love to eat all my meals."

"I love to have my desserts, my chocolate and cheese."

It's a great attitude to have - and definitely seems to be paying off for Nicole!
