1. Sharon and Ozzy Osbourne, 59 and 62

Sharon and Ozzy Osbourne will become grandparents in April, when son Jack's fiancee Lisa Stelly gives birth. The talk show host is thrilled at the prospect of having a grandbaby in the family. Sharon said: "That's what comes with being a grandmother. You can spoil, you can indulge, and then say, 'Okay, now let your parents be the ones to teach you right from wrong. I'm not. What do you want? Have it!' "
