From the Telegraph, London:

The Gatecrashers Tareq and Michaele Salahi with Vice-President Joe Biden in a screen image from Facebook page.
Like many suburban couples, Michaele and Tareq Salahi clearly aspire to greater things in life. The former cheerleader and her husband enjoy a spot of polo, run a winery near their home in Virginia, and like to rub shoulders with local movers and shakers. Indeed, when the most powerful couple they know of recently hosted a glittering party for a visiting friend, they decided to try and gatecrash. It would be their chance to mingle with the great and good, the stinking-rich and the well-connected. Who could possibly resist such temptation?
Well, most of us, actually. For the hosts of said party were Barack and Michelle Obama and the venue, naturally, was the White House. Yet somehow, on Tuesday, the Salahis managed to brazen their way past the Secret Service, the many layers of security screenings that one might expect at a do thrown by the most powerful man on the planet, and into the South Lawn tent where the state dinner in honour of the Indian prime minister, Manmohan Singh, was taking place.

And more about the party at The Daily Beast:
The most anticipated moment of the evening came when a member of the White House communications team emerged around 8 p.m. to brief the press on Michelle Obama’s outfit. “It’s a gold strapless dress,” the woman said, gesturing to her décolletage. “By Naeem Khan. N-A-E-E…” Khan, an Indian-born designer who started his own label in 2003, having thus been blessed with the Mobama fashion seal of approval, must have had a pretty good night.
“Michelle Obama is not following type,” said Wall Street Journal columnist Teri Agins, who predicted the strapless gown hours in advance. “We’ve seen her wear cardigans to meet Queen Elizabeth. We’ve seen her wear walking shorts on Air Force One. We’ve seen her wear Target and the Gap and White House Black Market; she’s just all over the place. And I just kind of think: I wonder if this has now set a new tone in Washington.”
