Jerry O'Connell and Rebecca Romijn are VERY comfortable with each other's potty habits -- in fact, they have a total "open door" policy when it comes to going #1 and #2.
Jerry was on Theo Von and Matthew Cole Weiss' "Allegedly" podcast Tuesday when they popped the bathroom question. Jerry's answer was completely candid. We're guessing Rebecca would say, too candid.
Bonus: Jerry also plays the fart game at home! Luckily, Rebecca dodges that fun. Check it out ... sounds like a great time, at least for Jerry.
