Pippa Middleton 'pregnancy advice spoof publication' in legal trouble

London, July 15 (ANI): A legal battle has exploded over a spoof publication, which imagines Pippa Middleton's advice on pregnancy and parenting.

The Duchess of Cambridge's younger sister is believed to have taken offence over the novelty book, written by Mat Morrisroe and Suzanne Azzopardi, the Independent reported.

The book, which parodies Middleton party-planning book Celebrate, started life as Twitter account @Pippatips, which mocked the 29-year-old author for her predictable party tips.

After gathering nearly 50,000 Twitter followers, the pair decided to turn their project into book "When One is Expecting: A Posh Person's Guide to Pregnancy and Parenting".

Middleton's lawyers Harbottle 'n' Lewis have written to the book's publishers, Icon Books, to demand the @Pippatips Twitter account be deleted. (ANI)
