Greenwich police have issued a kindly reminder ahead of tonight's Kylie Minogue performance at the O2.

Kylie will be playing tonight at the O2, which will have tens of thousands of fans flock to see the Aussie wonder.

But... big shows like this sometimes lead to bad behaviour.

Greenwich Police tweeted: "#ProjectServator plain clothes and uniform patrols around #GreenwichPeninsula and @TheO2 looking for suspicious behaviour.

"Keeping you safe before and during #KylieMinogue tonight. Someone didn't spot our plain clothes officers and lost his cash and stash! Enjoy the show!"

So our advice is to just enjoy the evening and leave your 'stash and cash' somewhere else, isn't Kylie Minogue enough?

Please make plenty of time to get too and from the O2, public transport will be full of sparkly fans!
