Kristin was struck by a piece of lighting equipment and fell to the ground, and according to sources for TMZ, the 43-year-old actress "smacked her head on the concrete during the fall."

Someone on the set called 911 around 5:07pm EST, and another witness said Chenoweth was hit "square in the head" and appeared to be "knocked out cold." The witness added, "I thought she was dead at first."

We still don't have a comment from her rep, but we're hoping she's ok!
