Caitlin Stasey covers her vagina with nothing more than a chilli emoji. Safe to say NSFW.

When I saw Caitlin Stasey’s Instagram story today, I shook my head, I sighed, I “tsk tsk”ed.

In the picture she stands, nude, her back to the camera, completely starkers save for a single strategically placed chilli emoji.

“She needs to cover up,” I thought.

Not because of the bare butt thing. (You do you, CStas.)

No, because of the sunburn.

The Los Angeles-based former Neighbours star's backside is neatly framed by a distinct tan line and her legs look, well, on the pink side.

Given the 27-year-old appears to be standing in a bathroom for the photo, I'm going to cross my fingers that she'd just cranked the hot tap a little too far to the left during her evening shower.

At 25, Emma Betts had to plan her own funeral. Post continue below.

Because as someone who sports a rather large, red scar on my shin where a dodgy mole used to be, I'm really hoping she hasn't overindulged on the rays this 4th of July.

Or at least that she won't make a habit of it.

Cover up in the sun, folks. Then go right ahead a strip off in the dark.
