Michelle Obama gets new hairdo as she meets Prince Harry at the start of his week-long US tour

Prince Harry joined First Lady Michelle Obama at the White House at the start of his week-long U.S. tour.

Michelle Obama welcomed the 28-year-old prince to her home on Thursday afternoon for a reception in honor of military mothers and their children after he caused a stir in Washington D.C.

As well as meeting Sen. John McCain at Capitol Hill, Prince Harry was welcomed by a bevy of grinning female staffers – who were promptly ushered back inside by police, according to their colleagues’ tweets.

“If all the women on Capitol Hill were dust bunnies, #princeharry would be a Dyson Vacuum. Every woman is gone. Every. Single. One,” Chris Mickey tweeted before the royal’s arrival.

When the women were asked to leave, sparking “grumpy faces” according to further tweets, they swiftly found other balconies over which to peer at the prince.

At his last event of the day, Prince Harry entertained US policy makers and wealthy donors at a British embassy reception.

Prince Harry chatted with 200 guests at the champagne bash hosted by British ambassador Sir Peter Westmacott and the HALO Trust anti-landmines charity before a dinner for 37 key influential donors and decision-makers.

In the sweltering humidity, the Prince repeatedly mopped his brow as he stood in a receiving line to greet each guest before working the room.

Among them were numerous American politicians, and President Barack Obama’s deputy national security adviser Anthony Blinken.

Guy Willoughby, director of the HALO Trust, praised Prince Harry’s determination to continue his mother’s work.

Prince Harry is visiting various areas of the U.S. from May 9 to 15 and wanted to include areas of the Jersey Shore that were devastated by Hurricane Sandy.

The roguish heir to the British throne will also attend a reception at the British Ambassador’s home and pay visits to Arlington National Cemetery to honor fallen soldiers and the Walter Reed National Military Medical Center, where Harry will spend time with wounded veterans.

The tour is not limited to New Jersey and Washington, as he will also attend a diplomatic reception in Denver, Colorado, as well as the 2013 Warrior Games in Colorado Springs -an event that benefits disabled veterans.

In New York City, Prince Harry’s visit will include an event promoting a community baseball program involving a new partnership with the Royal Foundation of the Duke and Duchess of Cambridge and Prince Harry, which bills itself as the culmination of the charity lives of Harry and his brother and sister-in-law, Prince William and Kate.

Harry will be promoting the charity’s “Coach Core”, which is an initiative dedicated to improving training facilities for inner-city kids.

Prince Harry also will take in a polo cup match in Connecticut.
