The future Duchess of Cambridge, who met William at St. Andrews University in 2001, embraced being 25 and donned black boots, fishnets, a black dress, and witch's cape. The royal-to-be was joined by her younger sister Pippa, then 23, and they partied at London's Mahiki Club.
Before rekindling with William, going out and looking good was all a part of Middleton's plan to get the prince back. At the time, a source told Us Weekly that Kate was devastated following their April 2007 split, but Pippa and her mom Carole urged her to get back out there to show William what he was missing.
After spending months apart — and after Middleton spent countless nights on the town — William and Kate then rekindled their romance in July 2007. In October 2010, William finally proposed to Kate in Kenya. The couple said "I do" in the most watched television event of the year in April 2011. They welcomed son George in July 2013, and expect their second child in april of next year.
