Glowing William and Kate Welcome the Obamas to the U.K.

Kate Middleton assumed her first royal duty this morning, just days after arriving home from her honeymoon in the Seychelles, when she joined her Prince hubby to welcome President Obama and First Lady Michelle to the UK.

The Obamas were first greeted by Queen Elizabeth and Prince Phillip before heading inside Buckingham Palace to hang with the Duke and Duchess.

Inside, America’s royal couple chatted with the UK’s royal couple about Will and Kate’s upcoming visit to California in July. Michelle and Katherine were overheard talking about the royal wedding and fashion. Love it!

In a rare honor, the President and First Lady were then given a 41-gun salute by Scots Guards in red jackets, who also played the Star-Spangled Banner.

Oddly enough, William and Kate were not included in the lunch and are not set to take seats at the grand State Banquet on Tuesday night. The Queen is really pushing this whole ‘you’re a duchess, not a Princess thing’.

About 200 royals and other dignitaries, including the Obamas are expected for dinner. The Pres and First Lady will spend two days at Buckingham Palace before heading out to other parts of Europe.
