Royal author Jerramy Fine says 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 ''Be as discreet as possible. Don't tell everyone in the nightclub that you're looking for Prince Harry 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.''
