Harry And Pippa Lookalikes Smooch

Many Londoners thought it was the day they had been waiting for — royal Prince Harry and royal sister-in-law Pippa Middleton showing some long-awaited PDA in the middle of London's Soho.

But no such luck. It's just a photo of two celebrity look-alikes who hit London streets on Wednesday to promote a book by artist Alison Jackson, an award-winning English photographer famous for her lookalike shots of celebrities. Her BBC comedy series, Doubletake, featuring celeb lookalikes in embarrassing or compromising situations caught on tape, made her popular in the U.K.

These particular doubles of the "happy couple," Roddy Walker and Hannah Williams, were shot in a variety of lovey-dovey (and even a few gropey) poses to promote Jackson's new book, Exposed!, which will feature photos of celeb doubles in the top news stories of 2011, according to the U.K.'s Daily Mail. Images in the book will include lookalikes of Kate Middleton, Tony and Cherie Blair, and David and Victoria Beckham.
