Ever since Michael Phelps welcomed his son Boomer [1] with fiancée Nicole Johnson in May, the proud parents have been flooding our Instagram feeds with adorable shots of the little one. In October, a precious photo of Boomer with food all over his face [2] was uploaded to his account with a caption that read, "I think I'm starting to like eating this real food😁😜." Michael is just one of the many famous dads who celebrated their first Father's Day [3] this year, along with John Legend [4] and Adam Brody [5].
