It was a wedding for the history books, and today (April 29) marks the third anniversary of Prince William and Kate Middleton's breathtaking nuptials.

Having recently returned from a three-week tour of New Zealand and Australia, the Duke and Duchess of Cambridge aren’t slated for a huge party, but they’ll definitely mark the occasion.

An insider told Us Weekly, "They chose to make low-key plans but it will still be a special day for them. They decided to do something low-key and in private before the tour and have been looking forward to celebrating."

As it turns out, Will and Kate are trying to recharge their batteries, along with their 9-month-old son George, as the upcoming months hold plenty to do.

"As always, summer is a busy time for the couple and this year will be unlike any other. Their schedule will be very busy in June, July and August."

Meanwhile, William and his brother Prince Harry are scheduled to attend the wedding of close friend Guy Pelly in Memphis, Tennessee this weekend.
