'Take a photo with a flash before you leave the house': Red-faced Ferne McCann cringes after accidentally flashing her perky posterior in a completely sheer gown

Ferne McCann proved once an Essex girl always an Essex girl as she left the star-studded guestlist in the shade on attending the London premiere of Batman v Superman: Dawn of Justice on Tuesday evening.

The former TOWIE star left little to the imagination as she slipped her svelte form into a rather risque little black dress which ensured she garnered more than a few double-takes.

Ferne, 25, refused to let the less than tropical temperatures deter from her racy outfit choice as she owned her look on arrival to the red carpet outside the Leicester Square branch of Odeon cinemas.

'Perhaps take a photo with a flash before you leave the house': Ferne McCann was left red-faced on Wednesday morning when she realised her entire dress was see-through at the Batman v Superman premiere 

Sheer bravery: The former reality star, 25, left little to the imagination as she rocked the red carpet in London's Leicester Square on Tuesday evening 

But the following morning, the I'm A Celebrity star was left cringing after realising her gown was completely see-through under the glare of the camera flash.

Posting a snap on her Instagram page on Wednesday morning, Ferne wrote: 'BatmanVSSuperman DawnOfJustice Prem last night. 

'Note 2 self...perhaps take a photo with a flash before you leave the house. My whole dress from @spottedonceleb went sheer fabulous evening none the less. #batmanvsuperman #dawnofjustice #whowillwin.' (sic 

The This Morning presenter was a vision of confidence in the barely-there number which was maxi in length and featured a sizable opening, exposing a generous eyeful of her long, lean legs.

She also offered onlookers a look at her perky posterior which was clad in only a teeny-tiny thong.

That wasn't all as Ferne also braved going braless in the plunging number which left her showing off more than she bargained for as her nipples were seen poking out from beneath the thin fabric.

Nipping out: Even the TV star's nipples were visible through the thin fabric as she braved going braless

Putting her best foot forward: Ferne ensured all eyes were on her racy outfit choice as she kept the additions very simple. She heightened her lofty form with a pair of three-strap stilettos

Close call: The Essex-born star was lucky not to expose her crotch as the sizable opening in the skirt of the dress twisted to one side

The former I'm A Celebrity contestant was lucky to not fully expose her crotch as the slashed skirt became twisted around one leg at one point and she came close to falling victim to the ultimate wardrobe malfunction.

She did everything in her power to ensure all eyes were on her racy outfit choice and kept the additions simple for that reason.

Ferne heightened her lofty figure with a pair of three-strap black stilettos which exposed her perfctly-painted red toenails.

Head-turning glamour: While all eyes were on the star-studded cast of the highly-anticipated superhero film, Ferne did her best to steal their spotlight

The only accessory she sported was a pair of tiny diamonds which decorated her earlobes while her hair and make-up was as flawless as always.

She boasted a light all-over glow while a rich purple-pink lip afforded her look a pop of colour and her hair favoured a poker-straight and slicked-back style.

It's thought Ferne McCann is in the throes of a new romance with England footballer Dele Alli and her dazzling display on the red carpet on Tuesday evening would have no doubt caught his eye.

Her smile says it all: Ferne put on the dazzling display after having been linked to England footballer Dele Alli

It's thought she's in the throes of a hot new romance and Ferne McCann was doing everything she could to catch England player Dele Alli's attention with a seriously sexy snap posted on Instagram on Tuesday.

Earlier in the day, Ferne posed seductively in her lingerie, sat on the floor of her bedroom with her long legs stretched out in front of her.

Having taken the photo in the mirror, she was able to flaunt almost every inch of her willowy frame and slight curves in the black and nude underwear.

The triangle bralet included a pretty black applique detail on the cup, but didn't distract from her small but perfectly-formed cleavage, while her stomach looked toned and trim.

But it was the Essex star's lovely legs that stood out in the image, her slender stems bent up to showed off her fake tan to full effect, her right pin notably darker than the left.

The This Morning presenter wore her long blonde tinted locks smooth and straight down her back, and she finished her leisurely look with a stylish choker around her neck.

Ferne was doing her bit to brag about a product, gushing over some fake tan as she wrote in the caption: 'L O V E my @bondisands self tan. Check out the difference Liquid Gold makes on my legs, smells shamaze! Easy to apply! And tan is toooooo good! Available from @bootsuk.'

New romance? Ferne is reportedly dating England footballer Dele Alli after the pair were linked after she admitted to enjoying a romance with a sportsman

She may have had her rumoured new beau Dele at the back of her mind, after reports made at the weekend suggested there is something going on between them.

According to The Sun on Sunday, the reality TV star and the Tottenham midfielder were seen kissing in nightclubs and 'acting like honeymooners' during a recent night out at London's Libertine Club.

A source told the publication: 'They did not stop kissing and did not care who saw them. There were fireworks and absolutely no doubt they were really into each other.' 

However, the football star has reportedly called for a cooling-off period because the news of their new romance began to spread among her famous friends.
