Award winning actress and healthy living guru Mischa Barton showed the world just what it takes to stay on top of your game and win all those roles.

By roles we of course mean opening the Harrods sale looking like she's missing her pile of big Issues.

And obviously by healthy living we mean swaying around London completely shitfaced looking like she has eaten nothing but ashtrays and dust for seven years.

The night started well enough, but towards the end Mischa commits the immortal celebrity sin - sunglasses in the dark.

Slow news day? You BETCHA!
