LONDON, April 29 (UPI) -- Prince William and Kate Middleton are "looking forward" to celebrating their three-year wedding anniversary Tuesday.
Sources tell Us Weekly that the Duke and Duchess of Cambridge plan to keep the celebrations "low key" for their special day.
"They chose to make low-key plans but it will still be a special day for them," an insider told the magazine. "They decided to do something low-key and in private before the tour and have been looking forward to celebrating."
The royal couple's anniversary comes days after they returned to London after spending three weeks touring New Zealand and Australia. A Buckingham Palace source said the couple plans to enjoy their downtime in London as summer "is a busy time" for them and "this year will be unlike any other."
William, 31, and Kate, 32, married in a lavish ceremony on April 29, 2011 at Westminster Abbey. The two welcomed their first child, a boy named George on July 22, 2013.
