One of the rules of any relationship is to be very, very careful what you do to celebrate your lovely lady's birthday. Especially if it's one of those significant milestone birthdays like 40. Jason learned this lesson in a very public and difficult way on 'Bethenny Ever After' (Mon., 10PM on Bravo).
At a lavish party he'd thrown together to celebrate Bethenny Frankel's big 4-0, she absolutely freaked out and lost her mind. She pulled Jason into another room where they talked about it while their guests looked around awkwardly.
