A duet with Grammy nominee Kelly Price at a pre-Grammy party in Hollywood on Thursday would become Houston's final performance. Houston was at the party with her daughter having a good time. But photos show a disheveled, bloated and agitated Houston leaving. She reportedly had blood dripping down her leg, scratches on her wrist and had to be escorted from the club.
However, people who knew her said she was simply sweating from her performance.
"There was nothing wrong. There was nothing wrong. She was singing, she was dancing, she was laughing, she was playing," Price said. "I'm going to remember her just like that because that's the Whitney I always had the pleasure of being around."
