Talk about a 'whoops a daisy!' moment.
Amanda Holden, 43, looked stunning in a delicate pink and white evening gown by Zeynep Kartalwith at the Collars & Coats Gala Ball for Battersea Dogs Home.
As she was being ushered onto the red carpet, the Britain's Got Talent beauty soon found the hem of her dress tangled up in her stroppy sandals.
Trying to set the situation out herself, Amanda forgot about her Angelina Jolie-esque thigh-high split - and wound up accidentally flashing her nude underwear at the waiting crowds.
Oops!

Thankfully Amanda papered over the mishap like a true professional, posing prettily with an adorable pooch who joined her on the red carpet.
The star took to Twitter before the event, telling her 1.6m followers: "Looking forward to @BDCH Collars and coats ball tonight! On my way x"
It's not the first time Amanda's flashed more than intended.
The cheeky star showed off her bottom on Twitter earlier this month.
Standing with her back to the camera, the mother-of-two wore a form-fitting purple dress that she had unzipped to just below her waist, showing off her impressive bottom.
She captioned the snap: "Guess who I interviewed today? #cheeky."
Well why not, eh?
