Kelly Osbourne with a mighty sweat patchKelly Osbourne with a mighty sweat patchCelebrities aren't perfect.

There, it's a bold statement that publicists and the like would have us ignore. But these pictures of famous folk with the dreaded sweat stain - something that plagues us all - confirm that they are, indeed, human (Sweaty Bettys).

Of course, there are those purists who've gone through crazy cosmetic surgery procedures to annihilate the glands that produce such stinky moisture, but for most people it's a just a hazard of life.

Sure, it's not a matter of life or death, but borrowing a lovely, amazing, stunning silk gown from a world-renowned designer and getting snapped with a circular stain around the pit is pretty mortifying (especially for the designer).

And of course, it's not just underarm drips that are revealed after a bit of light, cameras, action/ exertion/ plain old fear... Those evil beads can appear above the 'tash, down the back, around the crotch or anywhere on the chest - whether you're a bird or a bloke.

So, with summer arriving, and knowing that sometimes you'll choose a black dress or top purely to disguise the inevitable damp patch, we bring you some reassuring shots of perfect stars accompanied by the dreaded sweat stain.
