Jill Kelley, the Florida socialite who sparked the FBI’s discovery of the affair between David Petraeus and Paula Broadwell, scooped an invite to his daughter Anne’s high security wedding last month.

Jill Kelley – whose own alleged relationship with General John Allen has led to his nomination to lead American troops in Europe being put on hold – was invited to the wedding of Anne Petraeus and Matt Mauney, alongside her twin sister Natalie Khawam.

Pictures taken at the nuptials clearly show Jill Kelley, 37, standing just behind the elegant bride as she claps along to a band and mingles with guests said to have included Vice President Joe Biden – and illustrate just how far the ambitious brunette had infiltrated the high-powered political world.

Anne Petraeus has posted many pictures of her big day on her website fANNEtasticfood.com and in a post called We’re Married! the 30-year-old blonde, who is a trained dietician, gave a sneak peak at her reception – with Jill Kelley standing behind her in one of the photos.

Dressed in a smart black gown, Jill Kelley – who was the unpaid “social liaison” at MacDill Air Force base in Tampa – looked to be having a fine time at the wedding, held at Rosemont Manor in Berryville, Virginia, on October 13.

Frances Townsend, former Homeland and Counterterrorism security advisor to President George Bush, today even tweeted: “Sources tell me Jill Kelley & twin both attended the Petraeus daughter wedding last month whr 1 guest refrd 2 them as the Kardashian twins!”

The wedding was said to be a high security affair as pr service PR Log noted three days after the wedding that: “Berryville was abuzz this past weekend as residents noticed tightened security around Historic Rosemont Manor, the former estate of Virginia Governor and US Senator Harry F. Byrd, Sr.

“Rumors began circulating around town that Vice-President Joe Biden was at Rosemont. Others thought Secretary of Defense, Leon Panetta was visiting.

“Berryville Police and Clarke County Sheriff Department cruisers and several unmarked SUV’s were parked within the perimeter of the Rosemont estate, some noticeable from the road.”

General Manager Bill North acknowledged that while there was heightened security at Rosemont, all Rosemont clients are offered a high level of privacy and security, saying: “Obviously, this wedding has special significance because of General Petraeus’s presence, but there will be other weddings in the future that will have enhanced security.”
