Princess Kate Middleton has no issue poking fun at husband Prince William, especially when it comes to his lack of hair. Former royal butler Grant Harrold recalled "having a conversation about getting older" with Kate and William, both now 43, in his upcoming book, The Royal Butler: My Remarkable Life of Royal Service. The trio was sitting in the kitchen at the royal family's home at Highgrove in Gloucestershire, Harrold recalled in the memoir - set to be released later this month - when the discussion of balding came up.
