Many said that Prince William is “so handsome” in the photo. Others said that he has Princess Diana’s smile. A different user said that Prince William was like his mother.

According to Vicky Ward, Princess Diana and Prince William were not on good terms prior to the accident. The future king was starting to rebel from his mom to chafe at being a mama’s boy. Prince William was reportedly trying to be independent and he was so affected by his mother’s sudden death.
