Astor Lashed Camilla for Bedding Prince

Caustic socialite Brooke Astor lashed Camilla Parker Bowles for perpetuating the "family mistress business" by sleeping with Prince Charles even while he was married to Diana, reports the Guardian. "Your grandmother would be proud of you," snorted Astor, referring to Camilla's great-grandmother, who was believed to be one of Edward VII's many mistresses. Charles finally married Parker Bowles in 2005, eight years after Princess Diana was killed in a Paris car crash.

Diana believed Charles was still in love with Parker Bowles even as she was planning her wedding to the prince. "There were three of us in this marriage, so it was a bit crowded," Diana said in a notorious TV interview. The snotty letter to Camilla, now duchess of Cornwall, emerged yesterday in the Manhattan criminal trial against Astor's son, who is charged with stealing money from his wealthy mom as she slipped into dementia.
