Fifty Shades Darker's London premiere nearly had a wardrobe malfunction from Olivia Cox
The blonde bombshell took to the red carpet in a very revealing white dress with grey overlay with a plunging neckline.
The deep V nearly revealed the 28-year-old's modesty as she struggled to contain her assets in front of the cameras.
The TV personality and fashion and beauty blogger opted for unusual high heels with furry straps, but all eyes were on her cleavage as she repeatedly had to check that everything was covered as she posed for pictures.

Dakota Johnson goes braless as she takes the plunge at Fifty Shades Darker premiere
She paired a bold red manicure and pedicure with a fresh-faced make-up look and a smokey eye, wearing her blonde tresses in messy natural waves around her shoulders.
Posting a snap of her outfit on Instagram, Olivia said she was wearing a dress designed by her friend, Kelly Simpkin, who has previously dressed the likes of 35-year-old Fearne Cotton.
Elsewhere at the Fifty Shades Darker premiere, pop star Rita Ora flashed some major underboob in an eye-popping bejewelled gown and Katie Price cosied up to husband Kieran Hayler.
The premiere has also garnered negative attention in the form of anti-abuse protestors who were gathered outside the venue at Odeon Leicester Square representing the 50 Shades Is Domestic Abuse Campaign.

"Fifty Shades Darker is further normalising abuse and we are seeking to peacefully protest its messages and educate people about abusive behaviour," the campaign's founder Natalie Collins said.
A domestic abuse prevention expert herself, Natalie said: "Fifty Shades is more than just a fiction series, it is a social phenomenon.
"Its success evidence society-wide ignorance about abusive behaviour, normalises abusers and perpetuates damaging stereotypes about BDSM sexualities."
Fifty Shades Darker opens in cinemas tomorrow.
