There was nothing Tareq and Michaele Salahi did that was unexpected - except embarrass the US Secret Service by crashing a state dinner for the first time in modern history.

The couple, described as polo- playing socialites best known for their possible roles in the forthcoming reality- TV show The Real Housewives of Washington, penetrated several layers of security to join the dinner honoring Indian Prime Minister Manmohan Singh.

And they have the Facebook photos to gloat about their coup.

Their posts seem to chart their course through the night: Michaele posing with Marines outside near the White House doors, and with CBS News' Katie Couric and congressman Ed Royce inside the mansion. In the East Room, the Salahis cozied up to Washington, DC, mayor Adrian Fenty.

Once inside the dinner tent, they got pictures that appeared to show them with Pepsi chief Indra Nooyi, Obama chief of staff Rahm Emanuel and two with a grinning Vice President Joe Biden.

An official said it is unknown whether they met first couple Barack and Michelle Obama or the guest of honor.

The Salahis's other Facebook photos showed a penchant for posing with the rich and famous - with polo- loving Prince Charles, President Obama, former president Bill Clinton, John McCain, Oprah Winfrey, Bill Cosby and Buzz Aldrin. Michaele's photos show her as a former Washington Redskins' cheerleader and posing in a skimpy dress for a magazine.
