‘THE View” and “All My Children” had to evacuate their ABC headquarters on W. 66th St. yesterday when a fire alarm went off.

Actress Portia de Rossi was being interviewed live on “The View,” around 11:55 a.m., when the alarm went off. The show went to a commercial and replayed the last few minutes of a previously recorded episode while the building was evacuated.

It turned out there was no fire – and no injuries were reported.
