The cheeky model captured a selfie of her naked antics on the sand in an Instagram snap she captioned "California Dreaming."

The mum-of-two, 44, flashed a sultry glance as she lay chest-down on a bright blue towel.

Her curvy derriere could clearly be seen in the background as she took her cheeky picture with a camera phone positioned just above her face.

Looking set for a chilled day by the sea, Heidi had scraped her blonde hair into a cute bun and went make-up free.

Splashes of water could be seen on her shoulders hinting she'd recently taken a dip in the glistening waters.

The racy holiday image sent fans of the clothes horse, who recently designed a lingerie range for supermarket chain Lidl, completely wild.

One gushed: "Absolute perfection!!!!! 🌹🌹🌹🌹" as another put: "Amazing 😍 🔥."

A third hailed her: "Still the hottest Angel!" as another continued: "Thanks for the nice rear view 😗."

A bold fan then quipped: "Sweet cheeks!! 😙😙😙😙" in reference to her bum.

It seems Heidi jetted for some much needed me time following the wrap of her US TV show Project Runway.

Yet throughout filming she managed to keep fans entertained off-screen with her raunchy tongue-in-cheek antics on social media.

Earlier this month, she recorded herself dancing naked in the shower as she enjoyed a bathtime boogie.

Meanwhile in a recent interview with Ocean Drive Magazine, she opened up about going to nude beaches as a child and the influence it's had on her as an adult.

"I grew up going to nude beaches with my parents, so I’m a nudist," she told the magazine. "I have no problems with nudity at all. I’m very free.

"When I go to the beach, it’s in a very remote place where there are not a lot of people, and I like to go topless."
