Ferne McCann's gown turns totally see-through for red carpet flesh flash

FERNE McCann has gone from reality TV star to roving showbiz reporter, interviewing stars on the red carpet.

SHEER AMBITION: Ferne's dress showed off a lot more than she bargained for

But despite those credentials, it looks like the TOWIE babe is still naive when it comes to the effect flashbulbs have on sheer dresses.

Ferne was at tonight's Batman V Superman: Dawn Of Justice premiere in Leicester Square filming the A-list antics for This Morning.

The 25-year-old wore a dramatic black floor-length gown with a thigh-high slit and a plunging neckline.

However, it was the material which delivered the most raciness.

GOLDEN GIRL: Ferne had stripped off to showcase her tan

The moment a camera flashbulb went off – which was every second, this was a blockbuster premiere after all – Ferne's braless chest was instantly visible.

And when the Essex star turned around, her skirt turned see-through to expose her black thong.

However, fans had seen even more of Ferne's body earlier today, when she posted a selfie in her underwear.

SHE MEANS BUSINESS: Louisa wowed in her tuxedo-style dress

Boasting about her love for Bondi Sands Liquid Gold tanning oil, Miss McCann snapped herself wearing a sexy sheer bra with floral appliqué.

Judging by her red carpet nipple flash, she decided to do without her fancy lingerie on the night.

Ferne wasn't the only starlet turning up the heat at the London premiere.

Meanwhile, Gal Gadot – aka Wonder Woman – looked ravishing in a red velvet gown with bejewelled shoulder straps.
