Natalie Khawam and her twin sister Jill Kelley, the Florida housewife whose complaint over threatening emails revealed David Petraeus’ affair, have visited the White House three times in the past three months, it has emerged today.

In by far the most astonishing example of her determination to reach the top, Jill Kelley and Natalie Khawam were invited to two “courtesy” meals in the Executive Mansion mess hall as a guest of a White House aide, an Obama administration official has revealed.

Jill Kelley met the mid-level aide through her work with MacDill Air Force Base near Tampa, where she also rubbed shoulders with the military’s top brass, including General David Petraeus.

On one further occasion, she received a White House tour with her family, the official added.

This latest revelation shows just how far Jill Kelley soared from her humble beginnings as the daughter of Lebanese immigrants in Pennsylvania to the host of lavish military parties at her Florida mansion.

It also suggests that Jill Kelley was telling the truth in an email she wrote to a reporter at the Tampa Bay Times on September 28, in which she boasted of visiting the White House.

“Btw I was made the [honorary] Ambassador to US Central Command’s Coalition!” Jill Kelley wrote.

“In addition to that, I was just recently appointed to be the Honorary Consulate General to South Korea! I’m in DC today – just left from breakfast at the White House…. I really hope to see you soon!”

Further examples also emerged today of how the married mother of three, who is reportedly steeped in debt, has attempted to exploit her connections as she finds herself at the centre of the military scandal.
