He and his bride are currently riding the crest of a wave of popularity.
But Prince William has told the Queen that he'd like to delay becoming a full-time royal.
According to the Daily Mail, William, a search and rescue pilot on a three-year tour of duty, is keen to continue pursuing his RAF career.
The Prince currently carries out 40 public engagements a year.
This compares to his father's 500 and his grandmother, who takes part in 300.
He has 20 months to decide whether to sign up to for a second tour of duty or extend his current tenure by a shorter period.
His decision to stay in the RAF after 2013, when he was due to leave, has the full support of both his grandmother and his father, Prince Charles.
A source said: "The Queen, in particular, is very sympathetic to the Duke of Cambridge's feelings on the subject.
"She, more than anyone, knows what it is like to take on full-time royal duties at a young age.
