Lily AllenWho's see-through at GQ?Peek-a-boo, your dress has gone a little transparent...

And at the GQ Men Of The Year Awards, too.

We feel a bit sorry for the lady in question.

Because although this lass stepped out in style for the GQ awards, her frock decided to give a bit of a flash.

Or rather, did it clash with those camera flashes, which made it a tad less ladylike?

Frocks aside, there was a gaggle of gorge guys who turned up at the event, held at Covent Garden's Royal Opera House.

But it was the likes of Kanye West, James McAvoy and James Blunt who took home some GQ glory in the form of awards.

Go and see who the owner of that frock is, and the other stars who turned up at the event, in our gallery.
