While President Obama and First Lady Michelle Obama are in London, the Commander in Chief and his wife stopped by Buckingham Palace to visit with newlyweds Prince William and Kate Middleton.

The two power couples enjoyed a private 10-minute meeting at the Palace ... including a visit with Queen Elizabeth. The Obamas then watched a 41-gun salute by the Royal Artillery.

Although the President and First Lady were not officially invited to the royal wedding, looks as though there are no hard feelings.

See who else the presidential couple visited with ... after the jump.
