Kate Moss suffered an awkward wardrobe malfunction as she partied the night away for Diet Coke's 40th birthday on Wednesday.
The supermodel, 48, who is the creative director for the fizzy drink, had headed to celebrity haunt Annabels & Loulou's Members Club in Mayfair with pals and threw it back to her partying heydays by staying up till past 3am.
Not afraid to take fashion risks, Kate opted for a daringly low sheer dress which plunged all the way to the navel and showed plenty of cleavage.
But as the catwalk queen emerged from the club she suffered a wardrobe mishap with the dress exposing her chest due to its perilously low neckline.
Kate looked like she had a fab night on the town as she linked arms with a pal while leaving the venue.
Pairing the sheer dress with a black coat, the runway model added a boost to her height with black heels and accessorised with a black velvet bag.
While Kate partied into the early hours with the likes of Nick Grimshaw and Jaime Winstone, she has changed since her wild Primrose Hill glory days.
The star has now been clean and sober for more than four years.
Kate now prefers yoga, Netflix and a good night's sleep to hitting the town.
She also said she is now in bed by 11pm and needs a full eight hours sleep a night.
Speaking to Elle magazine, she said: "I hit the sack at 11pm-ish and watch Netflix before I go to sleep. I've just finished Sex Education – it's so funny."
She also said she is now in bed by 11pm and needs a full eight hours sleep a night.
"I deal with stress by doing yoga. It helps me concentrate on the here and now," she added.
Speaking to NBC's Megyn Kelly, she added: "I go to bed, I drink lots of water, not too much coffee, and I'm trying to cut down on cigarettes."
It's a far cry from her old partying days, during which she was nicknamed 'The Tank' for her heavy drinking.
Kate was said to have downed prosecco at 8am and glasses of wine and vodka at lunch.
And she's having a better time than ever, according to her friend, producer DJ Fat Tony, himself been sober for 13 years.
Fat Tony said in an interview previously: "Kate's been clean for over two years. Me and my sober mates now have a better time than we ever did when we used to drink and take drugs."
