Yeah, Kesha might not be "close" To Bill Cosby because she might have gotten creepy vibes from him, heard & suspected that the rumors about him, which were out long ago, were true, or as I sad, she was taught not to suddenly call up and exploit him for money.
Trump tried that same tactic on Joan Rivers when she didn't bring in a lot of money one task. He said, considering the people she knows, she should have brought in a lot. But, her daughter Melissa nailed him on that. Yes, Joan's friend were multi-billionaires: The Rockefellers, the Gettys, the Estee Lauder family. But Joan KNEW she should never try to hit them up for money. They would have hung up on her and she'd be ostracized from attending future events with them for crossing an invisible line.
