Miley Cyrus made a bet with Dr. Luke that 'Wrecking Ball' would top the charts. If she won, he'd have to buy her a luxury toilet.

Guess what? She did. And she's waiting on the uber producer to pay up!

Cyrus revealed to the New Yorker that Dr. Luke promised to purchase a Numi toilet for her if she held up her end of the 'Wrecking Ball' bargain. What's a Numi toilet? Well, it's got a motion-activated cover and seat, a bidet, an air dryer, a deodorizer, a heated seat, a foot warmer, illuminated side panels and it can stream music from your BlueTooth. Because when you're tinkling or No. 2-ing, all you want are some good tunes.

"Contrary to what he thinks, Dr. Luke isn't always right," Cyrus sassed. "I bet him him that 'Wrecking Ball' would go to No. 1 on the Billboard Hot 100 and it did. Now he has to buy me a $10,000 toilet. I'll be thinking of him every time I go."

Ain't that some s---?
