The Daily News caught up with former President Bill Clinton after a World AIDS Day symposium to ask him about daughter's engagement. Bubba said he was "very" excited about walking 29-year-old Chelsea down the aisle and said of her fiancee Marc Mezvinsky, "He's great. He's a great human being." (Apparently he had no comment on his future son-in-law's dad's various frauds related to the Nigerian black money scheme.) And for the very curious, the News adds that aides "cautioned that she might not be sporting her engagement ring immediately. The ring is in the shop getting properly sized."
