CHARLOTTE Church stumbles off with her knickers around her knees – after a drunken clinch at a charity bash.
The Welsh singer, 25 – a guest of honour at the posh polo event – had slipped behind a marquee for a tryst against the back of a van with boyfriend Jonathan Powell.
Fellow guest Jim Davies said: “I couldn’t believe it. She clearly had no shame.
“The pair started getting amorous like horny teenagers – until someone came past.
“She was so hammered she couldn’t even get her knickers up. She almost fell over.”
Mum-of-two Charlotte – sporting a new red hairdo – had earlier sung the Welsh national anthem to open Saturday’s bash at Glanusk Park, Powys, in aid of a kids’ hospital she is a patron of.
Her clinch with Jonathan, 24, at around 10pm was captured on video.
A security guard can be heard exclaiming: “They’re p****d off their f****** heads.”
Voice Of An Angel star Charlotte – who has sung for the Pope – split from her rugby ace fiancé Gavin Henson in April last year.
