Halle Berry, Carmen Electra and Jordan all looking a bit.... damp

- Celebrity sweat patches part I
- Celebrity sweat patches part II

You know how it is. You're walking down the red carpet, dressed in your best frock, cameras flashing, the crowd screaming... and then you realise that there's something evil lurking under the arm you were about to raise in a cheery wave. It's the dreaded celebrity sweat patch.

No one is immune, it seems. Damp Armpit Syndrome plays havoc with everyone's outfit, from the leopard-print mini of the Z-List to the Zac Posen gown of the A.

Of course, sweating is just a normal bodily function, and a natural reaction to the heat that comes with being in the spotlight. But that doesn't stop us pointing and laughing when we see celebs doing the sweaty betty - after all, it just goes to show that they're human too.

Go on, you know you want to - see who's who in our celebrity sweat patch hall of shame.

And if that's not enough for you, we've got more celebrity sweat patches - can you guess whose armpit is whose?
