[PHOTO] See Kate Middleton's 2007 Halloween Witch Costume During Her Break from Then-Boyfriend Prince William

The Duchess of Cambridge brought out her inner sexy in 2007 during Halloween when she was separated from then-boyfriend Prince William. Middleton rocked a sexy witch costume in London! The now soon-to-be mother of two and wife of Prince William, Duke of Cambridge seems to have her partying days behind her. But we can still reminisce!

That October in 2007, the wishful future Duchess partied with younger sister, Pippa, then 23, at London's Mahiki Club dressed in black knee high boots, a sparkly black dress, and a smile grinning ear to ear. No witch hat to be seen, but she still rocked the costume.

As Us reported back during their 2007 breakup, Pippa and mother Carole urged the then single Middleton to get back out there in a plan to get William back!

In pictures shown by UK's Daily Mail it seems as though the single witch was having a blast, free from the Prince. Middleton was photographed smiling and having a great time with friends.

In April of 2007, the couple split, however as PEOPLE's past reports state, the future parents of George and another little one on the way were said to have clandestine meetings together. "It's true that they have been seeing each other," a source told PEOPLE back in 2007. "They [never] loathed each other. It just wasn't working at the time."

In the name of Halloween, many fans of the couple even have the option to go as them for Halloween! Amazon is selling Prince William wedding uniform costumes, priced at $41.99! The costume showcases the infamous red suit and blue a blue sash.
