The soon-to-be wedded couple is planning to make their first official trip as man and wife in July when they travel to Canada.
Royal watchers say there are rumors they will make a stop in the U.S.
The royal family is said to have a master plan to introduce Middleton to the world.
"Going from obscurity to being one of the most photographed people on the planet, that's only a few weeks away for Kate," said Duncan Larcombe, a royal correspondent. "Kate's real problem, ironically, is that she's flawless."
There's also speculation that Middleton, who is a tennis fan, will take over trophy presentation duties at Wimbledon this summer.
Roughly a billion people are expected to watch the royal wedding April 29.
