P. Diddy makes his party guests wear slippers.

The rap mogul doesn't like outdoor shoes ruining the floors of his Miami mansion so shocked guests when he made them change their footwear before they entered a bash he recently threw at the property.

A source told National Enquirer magazine: ''A lot of girls complained about taking off their high heels, which were part of the outfit, but that's his rule. He doesn't want anyone scratching his gleaming wood floors.''

Diddy is famed for his partying and recently revealed he would love a night out with Britain's Prince Harry.

He said: ''I really can't wait to get to the UK as London is one of my favourite cities.

''I'm also hoping I'll get to catch up with Prince Harry while I'm there. He's such a cool guy and it's about time we hung out.

''I need him to take me to some of those wild Mayfair clubs!''

Diddy last met Prince Harry and his brother William at a Memorial Concert for their late mother Princess Diana in London in 2007.
