Cameron Diaz's make-up malfunction at premiere

Looking good from the front: Cameron Diaz

Great look, Cam just dont turn around, because a make-up artist could be about to find work hard to come by...

Cameron Diaz premiered new film Gambit in London on Wednesday with terribly applied concealer all down her back. Awkward.

The acne sufferer had blobs of chalky powder above her black top, which is worse than having a load of spots on show.

However, you're going to have to take our word for it as we can't publish the picture online (it's in today's paper page 17).

Later that night, Cam, 40, met up with Gwyneth Paltrow to launch a London club called Bodos.

The pair are close pals so Im guessing thats why she wore a jacket later.

No mate lets a friend go out looking like that.

Mind you, neither does a make-up artist. Or ex-make-up artist.
