'You have to be John Kennedy...'

I mean Jackie. Yeah, that's what I meant! Gov. James McGreevey's ex-wive claims in a new book that he told her right before his famous "I am a gay American" speech that she had to compose herself, saying, "You have to be Jackie Kennedy today."

Dina Matos McGreevey's Silent Partner: A Memoir of My Marriage, hitting bookstores May 1, also says he told her if she stayed at the governor's mansion until the last minute it would make her "look like white trash." Silent Partner is payback for McGreevey's The Confession, where the gay guv described sexual encounters with aide Golan Cipel, who says that never happened.
