Royal Wedding Dress Rehearsal for Chelsy and Pippa?

Feb. 28, 2011— -- Paparazzi clamoring for Kate on Saturday snapped shots of her sister Pippa instead. The younger Miss Middleton turned up at the aristocratic wedding of Lady Katie Percy, daughter of the Duke of Northumberland, to financier Patrick Valentine. Other guests included Prince Harry's past girlfriend, Chelsy Davy. Prince William and Kate were no-shows at the high society nuptials, held at Alnwick Castle, which stands in for Hogwarts in the Harry Potter films.

Neither Pippa nor Chelsy appeared to be attending with a date. The British papers claim the royal romance between Prince Harry and Chelsy is back on. The duo was photographed in the wee hours of Friday morning tumbling out of a London nightclub. But there was no sign of Harry at Alnwick on Saturday. The Daily Mail says he was cheering for England with his cousin Zara Phillips at a rugby game.

Both girls sported feathered fascinators that matched their electric jewel tone frocks. Pippa popped in a bright pink-flowered headpiece that coordinated with her fuchsia dress and black flounced coat. Her fascinator was created by Vivien Sheriff, the same British designer who made the chic piece Kate wore Thursday in Anglesey to christen a lifeboat.
