Prince Charles had affair with Barbra Streisand
Everything would go the other way.
Prince Charles, before marrying Princess Diana, could have married a famous singer. It is not known how the history of the British royal family and the personal life of Prince Charles could have developed if she 'played her cards right'.
Once Barbra Streisand said that she could move Diana and marry Prince Charles herself. According to the actress, it was prevented by the fact that she was very nervous next to him, and further rapprochement did not happen.
