Uptight ‘Idol’ judge Connick to J.Lo: Welcome to ‘Dumpin’ Your Dollars!

Fed up with jokey JENNIFER LOPEZ’s perennial potty mouth, “American Idol” judge HARRY CONNICK JR. decreed she needs vocal toilet training – so he bought a toddler-size porta-potty and made her agree she’d poop in … er, sorry, that’s “pop in” … one hundred buck$$$ every time she dumps an F-bomb.

Said an insider: “J.Lo thinks it’s hilarious! Plus, all the proceeds go to charity, and she and Harry now have the entire staff and crew ‘donating’ dough whenever they drop a dirty.

Money’s literally being thrown in the toilet, but it’s all for a good cause.”

Talk about being FLUSH!
