While on Letterman, Heche called her ex hubby a "lazy ass" and spent most of the interview mocking him.
"He goes out to the mailbox and he opens up the little mailbox door and goes, 'Oh! I got a check from Anne! Oh! I got a check from Anne! Yay!'" she told the audience.
Needless to say, her ex wasn't too thrilled about the jokes and so he's firing back at her now.
"After coming home from showing two different clients two different condominiums, I was disturbed to see Anne taking out her personal frustration on the father of her child on national television," Laffoon, 35, an employee with Los Angeles real estate company Hilton & Hyland, tells Us Weekly.
Clearly someone is bitter over spousal support. This is why celebrities shouldn't get married, they're all nuts!
