Discretion is the key to winning the heart of Prince Harry
The writer - who moved to the UK in the hopes of meeting and marrying Harry`s cousin Peter Phillips and chronicled her quest in the book `Someday My Prince Will Come` - has offered tips to the legions of `Harry Hunters` hoping to land the British prince.
She told website bettyconfidential.com: "Be as discreet as possible. Don`t tell everyone in the nightclub that you`re looking for PrinceHarry because you plan on falling in love and bearing his children (even if you believe this to be true).
"Don`t be discouraged if people tell you that meeting Harry is unrealistic. Winning `American Idol` is also pretty unrealistic - but if you believe something is your destiny, don`t let anyone stop you from trying."
Jerramy also advised Harry`s admirers to brush up on their potential future in-laws and to take an interest in the 27-year-old prince`s hobbies.
She added: " Read all you can about the House of Windsor. Make sure know who`s who, how everyone is related, their official duties and the charities they support. (Tatler, Hello and Vanity Fair can often be better and more up-to-date sources of information than magazines like Royalty and Majesty.)
"Hang out in the village of Tetbury - you never know if Harry might be home from a military mission and stopping by Highgrove to visit his Dad.
"Learn to love polo and rugby. If Harry`s not playing one, he`s watching the other."
