She hit the town to attend a charity bash on Tuesday night.
But Lizzie Cundy grabbed attention for all the wrong reasons as she headed home from the PINK London party at Tropicana beach club.
The former WAG, 46, turned out at the bash, which kick-started Breast Cancer Awareness month, in a headturning gold dress.
Lizzie’s frock showed off her ample assets with a low-cut neckline – but the racy number was her downfall later in the evening.
The brunette hopped in a cab but accidentally suffered a major wardrobe malfunction.
Lizzie flashed too much as her dress fell down, exposing her nipple.
The star didn’t appear to realise what was happening and maintained her big smile as she headed off in the taxi.
Mum-of-two Lizzie was married to former Chelsea and Spurs defender Jason Cundy for 16 years and made a career as a self-appointed spokesperson for WAG culture.
In early 2010, she discovered her husband was having an affair with an opera singer he’d met by chance on a train and with whom he had fallen in love.
She told the Mail in an interview at the time: ‘I just didn’t see it coming. At first, I didn’t know how to handle it. After all the years together, I thought we were a successful team – that we would grow old together.
‘This just shows that it could happen to anyone – and I didn’t know about it for ages. I only found out because a family member overheard a conversation between Jason and this girl.
‘I felt physically sick, but I kept telling myself that it was all a mistake. When I confronted him, I said I know something’s going on. He looked at me and I just knew it was true.’
