Oprah, Barbara Walters Go to War Over Pippa Interview 1Oprah Winfrey and Barbara Walters are reportedly locked in a titanic battle to land the first U.S. interview with Pippa Middleton, sister of Kate Middleton, wife of  Britain’s Prince William. So far the bidding is at $500,000.

Oprah’s struggling network, OWN, has reportedly been directed by Oprah herself to “pull out all the stops to secure her first TV interview,” a source told London’s Sunday Mirror.

ABC’s Walters is pushing executives at her network to offer six-figures for the interview and NBC is also trying to land Pippa for the Ellen De Generes show.

The heavyweight television interview queens want to host an hour-long special with Pippa, who shot to international fame as the shapely bridesmaid to her sister at her April wedding to William.

Pippa, 28, is apparently open to interviews. She is currently working on a book on how to throw the perfect party. Both Oprah and Walters are said to be negotiating with Penguin, Pippa’s publisher, to land the interview, according to London’s Daily Mail.

Pippa landed an estimated $600,000 advance from Penguin for the book, beating out HarperCollins and Random House’s subsidiary, Cornerstone.

The book will be about entertaining and how to throw the perfect party. “It’s not just about being the perfect hostess, it will also include recipes and information about how to host different types of events,” a source told the Mail last year.

Before becoming an international sensation, Pippa worked for a London-based events company Table Talk. She also edits The Party Times, an online newsletter on her parents’ Party Pieces website.

Pippa is expected to donate any fee to charity.
