Why were you surprised. I have seen a lot of celebrity Godmoms.
There's Sophia Loren (and did I mention Sophia Loren? she has done quite a few), Rosie O'Donnell, The Olsen twins, Kate & Tristan (The Bachelorette marriage couple), and a LOT more I don't remember now.
It didn't seem like something Whoopie Goldberg would want to do. Having groups of women now is getting fashionable. I think it was Allure Of The Seas that had several women athletes from the Olympics. Then Norwegian Breakaway had the Rockettes, and now the Getaway will have the Miami Dolphin cheerleaders. Of course the latter two groups are constantly changing so does that mean that a cheerleader or rockette in 2018 can say she is a godmother of the Breakaway or Getaway?
