The Britain’s Got Talent judge was attempting to gracefully climb out of a cab when she flashed her nude pair of knickers.
Amanda Holden, 46, looked incredible at the Attitude Magazine Awards, in a flesh-flashing, thigh-skimming ensemble.
Her daring dress featured a cut-out panel from her right shoulder to her lower stomach and clung to her slender physique, showing off her super slim limbs.
Amanda let her jaw-dropping outfit take centre stage and opted to style her blonde locks into short choppy waves.
The TV star’s outfit wasn’t the only thing that shocked her fellow partygoers.
The mum of two made a lewd speech when she accepted her award for Honorary Gay, saying that she “loves c**k”.

After beginning her speech saying accepting the award is like receiving “an MA, master of a**e,” Amanda joked: “And my girl friends know that’s how I got these diamonds baby.”
She later said: “It’s always struck me as a little bit odd that I’m not in fact gay, because I absolutely love c**k. I do, I do.
“And now that I am an honorary gay, I can’t wait to have honorary gay sex. Though I suppose, being an honorary gay is not actually being gay.
“So honorary gay sex means not actually having sex. In which case, I’ve been married to my husband for 15 years and I’ve got two kids, so I’ve been having honorary gay sex for years.”
She also joked about “going cottaging” – a lewd oral sex act which takes place in a public toilet.
“The last thing you would be expecting if you were on Hampstead Heath hiding in a bush, is a bush,” she added.
Amanda rounded off her shocking speech on more serious issues, talking about foreign countries who continue to discriminate against homosexuals.
