The singer refuses to plonk her most valuable asset on toilets unless they are fitted with her own germ-resistant seat.
When she hears Her Majesty gets a special throne built for her on state visits, that might well end up on J-Lo’s rider too.

J-Lo is also said to request loo roll made of the finest cashmere.
