Actress Isabelle Cornish wears a VERY racy shirt

Isabelle Cornish is no stranger to expressing herself online.

And on Friday, the 27-year-old actress shared three photos on Instagram, in which she posed in a naughty t-shirt.

The oversized green top featured a retro-style white graphic that read, ‘Sex. Breakfast of champions. ‘

The future SAS Australia star showed off her nimble form in the photos, easily lifting one leg in the air.

The Puberty Blues actress wore a pair of tiny yellow shorts, which clung to her toned figure as she twisted into a series of gymnastic poses.

She wrote in a caption next to the pictures: “My mom always wore cheeky shirts.”

“I remember one day she picked me up from school with a f *** shirt on. It had 100 different words, but move your body is good for your health, ”she added.

Many of Isabelle’s fans commented under the pictures, enthusiastically endorsing her love of racy shirts.

“This t-shirt is everything. And yes, your mom is a queen of the sky. I love it, ”one user wrote while another joked, “There’s a breakfast I could get around to. ”

Isabella recently finished filming the second season of Seven’s SAS Australia in May alongside her fellow celebrity rookies.

The competition’s new lineup features a mix of famous and controversial entrants including Sam Burgess, socialite Brynne Edelsten and TV chief Manu Feildel.

SAS Australia season two will air later this year on Channel Seven.
