It was a scary moment for Wendy Williams, her staff and viewers during her talk show Tuesday morning when she collapsed live on television.While introducing a segment, Williams appeared to misspeak and lost her footing. She was able to regain her balance, before she started wobbling again. She looked alarmed and then collapsed to the floor a few seconds later. Crew members were seen rushing to her aid before the camera cut to a commercial break.Viewers were quick to post video of the scary moment on social media. After the commercial, Williams returned and told the audience she passed out after overheating in her Halloween costume. "That was not a stunt," the 53-year-old host said. "I'm a champ and I'm back."Williams was able to continue hosting for the remainder of the live show.
