Kate Middleton, 29, is going to need some pointers when it comes to entering the royal family.

The royal financee sat down to lunch on Wednesday at Koffmann's, a restaurant in London's exclusive Berkeley Hotel, with none other than Prince William's stepmother, Camilla, Duchess of Cornwall, 63, reports UK's Daily Mail. The two ladies were joined by Middleton's younger sister, Pippa, and Camilla's daughter, Laura Lopez.

The fact that Middleton carried a notebook with her during the meal led some to believe that her future stepmother-in-law was helping her plan the royal wedding, which will take place at Westminster Abbey on April 29. Witnesses in the restaurant distinctly heard Camilla say, "if I can give you one bit of advice …."

Camilla knows a thing or two about advising future royals. Thirty years ago she sat down with Lady Diana Spencer to advise her about marrying Charles, Prince of Wales. —KIMBERLY STEELE
