He made deadline! Posties marry

CHRISTINA Amoroso, executive editor of Bustle, and Michael Riedel, co-host of “Len Berman and Michael Riedel in the Morning” on WOR Radio, got hitched yesterday in Atlantic Beach, LI. They met 10 years ago at The Post, where Riedel was the Broadway columnist and Amoroso was a cub reporter. She shot through the ranks and eventually became one of his editors.

Said Riedel: “I had to marry her so she couldn’t fire me!” The couple remain Posties at heart. We hear that the guest list for the nuptials included Berman, music legend Clive Davis, sportscaster Warner Wolf, Barry and Fran Weissler, Margo and Jimmy Nederlander and Bob Wankel. We’re told the “best man” was author Imogen Lloyd Webber, daughter of Andrew.
