LOS ANGELES — A philanthropist and former entertainment exec has become the latest in a string of alleged victims to accuse entertainer Bill Cosby of sexual assault.

The accusation by Cindra Ladd, the wife of former 20th Century Fox President Alan Ladd Jr., came on the same day the entertainer pulled out of another scheduled concert performance, this time in Bakersfield, Calif.

In an essay posted to the Huffington Post on Monday, Ladd wrote she met Cosby in 1969 in New York when she was a 21-year-old single woman working for the late film producer Ray Stark.

Ladd wrote that Cosby asked for her number, and she gave it to him.

She said she met him one night before a movie outing at an apartment he said belonged to a friend of his. After she complained of a terrible headache, Cosby told her he had a “miracle cure” given to him by a doctor. He gave her a capsule, saying she could trust him.

Ladd wrote that she doesn’t recall exactly what happened because it remains “a blur.” But she said she awoke the following morning nude in bed at the friend’s apartment.
