Mischa Barton underwent a bizarre makeover for a charity ball in London at the weekend – ditching the glamour for the garish.

The usually stylish actress went overboard on the eye liner, creating a look more suited to Amy Winehouse than a Hollywood beauty.

And if that wasn’t bad enough, she also donned a wacky leafy headband that wouldn’t look out of place on a jungle-dwelling tribeswoman.

Even the grey dress appeared to be stolen from the wardrobe of a librarian.

Let’s hope this mad concoction of clothes and makeup was a mere one-off for Mischa.

Maybe she thought the theme of the ball was fancy dress.
