Jennifer Lopez refuses to use any toilet unless it is fitted with her own special seat, according to reports.

Apparently the star makes sure she always has access to her own potty cover to ensure a germ-free bathroom experience.

A source told The Sun newspaper: “Jennifer is a clean-freak and doesn’t like putting her bum on any toilet unless it’s on her own custom-made seat. It’s a cover made to fit any loo.”

The actress and singer is well-known for wanting to protect her prize possession.

Jennifer’s ex-boyfriend Ben Affleck was rumoured to have purchased a gem-encrusted portable device for her to use while travelling the world.

At the time of their dating, the actor allegedly paid $105,000 in 2003 for the gem-studded toilet seat, featuring rubies, sapphires, pearls and a diamond.

A source told The National Enquirer: “The stones are set inside the plastic, so Jennifer’s behind won’t get scratched.”

He told a friend: “Jennifer is my princess and she deserves only the best — even when it comes to toilets.”

Designed by Ben himself, the report added that the stones were set inside the plastic, so Jennifer’s behind wouldn’t get scratched.
