Britney Spears has been traveling under a number of aliases over the years. Steve Dennis reveals in a new biography, “Britney: Inside the Dream,” that her favorite fake names include Ms. Alotta Warmheart, “because she had such a warm heart”; Mrs. Diana Prince in honor of Diana, Princess of Wales; Queen of the Fairy Dance, “because she was the dancing fairy”; and Mrs. Abra Cadabra “for no apparent known reason.”
