She's previously struggled with her weight issues, often covering up as she yo-yo diets.

But this morning Lauren Goodger obviously felt confident with her body as she showed it off in a black leotard underneath a sheer dress.

And she revealed even more of her body with the low cut of the bodysuit emphasising her cleavage.

But although the outfit seemed rather bad taste, especially in today's heatwave, fans can breathe a sigh of relief as she was merely in fancy dress for a special TOWIE bash.

The cast of the show gathered together to celebrate Joey Essex's 22nd birthday earlier today.

He decided to hold an eighties-themed bash two weeks before his actual birthday, thought to be to keep with in the TOWIE filming schedule.

His girlfriend Gemma Collins posed in her skimpy number as she joined the likes of Lauren Pope, who was yet to change into her themed outfit.

Tom Pearce and Billie Faiers were also on hand ready to party the afternoon away.

And birthday boy Joey showed up with girlfriend Sam Faiers in tow as they wore matching shorts.

It was unclear whether Essex was already in his chosen garments for the night as he wore some peculiar tiny shorts, which seemed dated.

But it seems to be his new staple style as just the night before he wore a similar get-up seriously for a family meal with Faiers.
