Bethenny Frankel Pees in a Bucket at Her Wedding (VIDEO)

The big day has finally arrived on 'Bethenny Getting Married' (Thu., 10PM ET on BRAVO). And as the old adage goes, necessity is the mother of invention. On her special day, Bethenny Frankel has a deep necessity to pee. Immediately.

The (pregnant) bride has already donned her gown, and traipsing to the bathroom means walking through her wedding guests in her dress. Sean suggests a bucket. "Pee in a bucket at my wedding? That's so sleazy!" says Bethenny.

But there's no other choice. Sean and Julie maneuver her over the pail. Julie has the task of taking off Bethenny's underwear, while Sean is holding up the dress.

"Outside, I was like, 'Sure, whatever you want, sweetie.' Inside I was like, 'Whaaat?!'" says Sean.
