The Dynasty legend had dashed backstage to switch outfits inbetween scenes of An Evening With Joan Collins when she was caught in the blackout - leaving her lost in the dark.
Luckily her husband Percy Gibson came to her rescue and helped to guide her in the right direction to complete her production.
She tells the New York Post's Page Six gossip column, "Thankfully, my husband, Percy, was there to give me a hand. Otherwise, I'd have been stuck."
Collins wrapped up her New York stage stint on Saturday (27Nov10).
