Amy Winehouse can?t help but destroy everything she gets close too, as an extremely worse for wear Sadie Frost staggered out of the ?Back to Black? singers house, after a short 90 minute party.

The fashion designer/actress entered Amy?s house at midnight on Monday looking glamorous with her on-off boyfriend Kristian Marr.

When she left Sadie, 43, looked a mess, with her dress undone and her underwear on display as she piled in to a taxi.

A source said: “The zip of her dress wasn’t done up properly and her jacket was tucked into the back of it. She was in a real state.

“Oddly, she left clutching a box full of junk, which had ‘make-up/skin care bits’ written on the top.

“When they came to leave, they couldn’t open the front door.

“Amy said she had lost the key after locking it, so there was a bit of a panic as they tried to work out how they were going to get out.”

Sadie is apparently Tee Total, but as thins proves when you go to the Winehouse, don?t expect to come off well.

The mother-of-four is a member of the infamous Primrose Hill set - which also includes supermodel Kate Moss, Rhys Ifans and British actress Davinia Taylor.
