This is probably one of the better known cases of later-life pregnancy on this list; anybody who's familiar with Halle Berry's career will know about her private life and her situation when it comes to children; she was a Hollywood sex symbol of the 90s and 00s, and speculation and gossip about her was tabloid fodder for years.
Berry was 41 when she had her first child, a daughter named Nahla, who was planned. She wasn't intending on adding to her family, but it happened quite by accident at the age of 47 with the birth of her son, Maceo. Speaking on Ellen DeGeneres's show, Berry explained that the second pregnancy was a total shock. In fact, it should have been biologically impossible; Berry was experiencing early pre-menopausal symptoms at the time, so getting pregnant was the last thing she expected to happen.
