It's coming up to 20 years since Princess Diana's death, and a lot of things in the Royal Family have changed.

Perhaps the most notable change is Prince William marrying Kate Middleton and starting his own family.

Though Prince William has grown a lot since the death of his mother, he still misses her and thinks about her every day. Recently, His Royal Highness gave a candid interview to GQ magazine and spoke of how he wishes his mother were here to see his kids. The interview also included a new candid picture of the family having fun outside.

"I would like to have had her advice," Prince William said of his mother, who was killed in a car crash in Paris in 1997. "I would love her to have met Catherine and to have seen the children grow up. It makes me sad that she won't, that they will never know her."

"I am in a better place about [her death] than I have been for a long time, where I can talk about her more openly, talk about her more honestly, and I can remember her better, and publicly talk about her better," HRH said. "It has taken me almost 20 years to get to that stage. I still find it difficult now because at the time it was so raw. And also it is not like most people's grief, because everyone else knows about it, everyone knows the story, everyone knows her. It is a different situation for most people who lose someone they love, it can be hidden away or they can choose if they want to share their story."

As for his own family, Prince William says he and Kate are on the same page when it comes to raising the kids.

"I could not do my job without the stability of the family. Stability at home is so important to me. I want to bring up my children in a happy, stable, secure world and that is so important to both of us as parents. I want George to grow up in a real, living environment, I don't want him growing up behind palace walls, he has to be out there. The media make it harder but I will fight for them to have a normal life."
