Girls AloudGirls AloudWe thought Charlotte Church was Girls Aloud's worst critic...

But someone else is not a big fan either.

Now, we all know koala's can't talk, but one little bear made sure that actions spoke louder than any words...

By peeing on two of the girls. Strewth.

The unpleasantness took place during an interview - with the girls, not the koala - at a Sydney zoo.

An eyewitness told the Daily Mirror: "The girls were at Sydney's Tooronga Park Zoo being interviewed.

"As they cuddled the koalas, two of them got peed on and had to change before their next interview."

Well, sometimes you just don't fancy a cuddle - even if it is from some gorgeous members of a girl band.

We wouldn't want to cause further indignity.

The band are currently touring Australia to promote their album Chemistry.

And as well as the embarrassing wee incident, there were also difficult questions about a rumoured split to deal with.

Sarah Harding reassured fans and said: "We're planning a tour of Australia and New Zealand for next year. We intend to be together for quite a while."

We've got one word for you, ladies: travel wash.

Yes, we know that's actually two words, but Kath And Kim fans will forgive us.
