After overshadowing her sister Kate Middleton at her wedding to the future King of England, Pippa Middleton went into hiding. (At least she wasn't photographed publicly.)
Until Monday, that is, when the sister of Britain's Duchess of Cambridge watched a match at the French Open between Maria Sharapova of Russia and Agnieszka Radwanska of Poland.
Before her sister's wedding, only Royal Watchers knew who Pippa Middleton was. When she took her seat at Roland Garros to watch the Open, all eyes at the stadium were on her.
Philippa Charlotte "Pippa" Middleton is the younger sister of Kate Middleton, who became the Duchess of Cambridge when she married Prince William on April 29, 2011.
Pippa is still single, but has been linked romantically to an English cricket player, as well as to Prince Harry (although that seems to be mostly wishful thinking on the part of the British press).
A professional event planner, 27-year-old Pippa served as maid of honor at Kate's wedding, but is quickly becoming a celebrity in her own right.

Pippa and Kate's parents founded the company Party Pieces in the 1980s, which was so profitable, it turned them into self-made millionaires. It has been reported that the Middletons want Pippa, a professional event planner to take a prominent role in the business.
The Daily Telegraph reports that she is a part-time editor for the web magazine "Party Times," which is a spinoff of Party Pieces.
