Kate & William COMING TO AMERICA!

Conquering the United States is next on Kate Middleton and Prince William's royal to-do list

- 

Roll out the royal red carpet! For the first time in eight years, Prince William and Kate R Middleton are traveling to the United States. On July 20, it was announced that the Duke and Duchess of Cambridge, both 40, will visit Boston this December for the second annual Earth shot Prize awards ceremony.

Now Life & Style can reveal that the duo plan to use the event which was launched by William to help effect positive environmental change - as a springboard for a larger trip that will take them all over America in service of their various charities. "Unlike their recent, not-so-successful Caribbean tour, William and Kate have a big say in their speeches and are going to be doing things their way this time," says a source. "William is confident that they'll nail it."

OH, BROTHER!
