Appearing on "Live! with Kelly & Michael" on Friday, the pixyish actress offered details of the accident, which happened during a New York location shoot.

When she woke up, co-star Josh Charles was holding her hand.
Said Chenoweth: "He's my angel."
Chenoweth, 44, said she continues to recover from a skull fracture and rib, neck and back injuries. But she called herself "blessed" the mishap wasn't worse.
Although forced to withdraw from her recurring role on "The Good Wife," she'll appear on its Sept. 30 season premiere.
