It was a scary moment for Wendy Williams fans when the daytime TV talk show host fainted on-air. She was able to bounce back quickly, assuring fans after a short commercial break that she was OK. But rumors circulated about what really caused her to faint ... and so she took to her show to try and set the record straight. During a segment of her show on Wednesday, Williams said that she started to feel faint about 48 minutes into the show and soon felt hot and dizzy. She went on to say that doctors tests showed that her blood pressure and heart rate were fine, putting to rest any concerns that she had a stroke or heart attack.
