A spokesperson for the Beckhams says the wet patch on Victoria's jeans this week was a result of 'the most unfortunate positioning of a split drink'.
Eyebrows were raised when the designer was pictured leaving a party in London - looking worse for wear.
The wet patch could be seen on both the front of her crotch and the back.
Their rep said: 'It was the most unfortunate positioning of a spilt drink, whilst Victoria was sitting down – thankfully it was not a 'dampener' on what was a fantastic night.'
Victoria hasn't mention the incident on Twitter:
