Princess Diana Remembered: A Look at Princes William and Harry, Then and Now (GALLERY)
Diana, the beloved Princess of Wales, was killed in a car crash 15 years ago, on August 31, 1997; her Mercedes smashed into a wall after reportedly being chased at a high speed by photographers on motorbikes in Paris, France.
To honor Princess Diana, Celebuzz is taking a look at the princes' lives, from their adolescent years to today.
Harry and William were just lads when their mother died -- Harry was 12; William was 15. But they aren't the only ones carrying on Diana's legacy.
Her brother Earl Charles Spencer recently welcomed a daughter and named her after the late royal. His wife, Karen Spencer, gave birth to Lady Charlotte Diana on July 31, 2012.
“We hadn’t settled on a first name before the birth, but Charlotte is a name we both loved, and it really suits her. We knew that as soon as we saw her," Spencer said. “And, though it’s been 15 years since Diana died, I still miss her every day, and I very much wanted her commemorated in the naming of our daughter.”
Milestone moments are sensitive for the family -- Prince William once admitted that he wished his mother was present for the biggest day of his life thusfar: his marriage to The Duchess of Cambridge, Kate Middleton.
He told Katie Couric, "It's the one time since she's died where I've thought to myself it would be fantastic if she was here, and just how sad really for her, more than anything, not being able to see it. I think she would have loved the day, and I think, hopefully, she'd be very proud of us both for the day."
He added, "I'm just very sad that she's never going to get a chance to meet Kate."
