The Princess of Wales taking the spotlight delights husband Prince William - but there is one thing that bothers him, according to a royal expert.
During William's parents' ill-fated marriage, King Charles is said to have grown increasingly jealous of Princess Diana's massive popularity.
In the early days of their union, Charles would often be overshadowed by his wife, with crowds shouting to talk to Diana instead of the future king - leaving him reportedly "frustrated".
However, royal expert Roya Nikkhah says there is a "striking difference" between William's parents and his relationship with wife Kate when it comes to their popularity.
She told True Royalty TV's The Royal Beat: "Charles was always very upset when Diana had eclipsed him, which was all the time. William is delighted by the fact that people warm to Catherine.
"William is comfortable with that. I have heard him talk about Catherine's work and how excited he is about it, and he loves that she is getting traction."
However, the Sunday Times royal editor added there was one thing that William does not always enjoy.
She explained: "The only thing I know that does slightly bother him is when he is cropped out of photos.
"You will find very often they will do a joint engagement and the front page of the news the next day, it is as if William was never there!"
Meanwhile, Hannah Fernando, editor of Woman and Woman and Home Magazines, said: "These two seem very much a team. Catherine has no wish to eclipse him. She is coming into her own because she is actually brilliant.
"She has taken on this life, opened her arms to it, and learned along the way what she needs to do. I think he is delighted by that, and I don't think he is worried about her eclipsing him."
It comes after reports that history could be repeating itself, with speculation that Kate had upstaged Charles and now-wife Queen Camilla.
Kate's unexpected appearance at the Chelsea Flower Show garnered far more buzz than when he and Camilla visited hours later.
However, royal expert Robert Jobson has explained that Kate in fact has her father-in-law's blessing to "steal the limelight" - and it's down to him now having the top job.
Writing for MailOnline, he explained: "Whilst it is Charles' head that wears the Crown, it is William, Catherine and their children that will steal the limelight. They are bound to. And it is right.
"This time, it will be with Charles's blessing – for he knows for the monarchy to survive it must be relevant to the younger generation."
