Nov. 16, 2010— -- "Waity Katie" must wait no more. A mere eight years since the couple met, Britain's Prince William is officially engaged to Kate Middleton, royal officials said today.
Watch the full story about the royal engagement on a "Nightline" special edition, "Nightline: A Very British Wedding," TONIGHT at 11:35 ET
"The Prince of Wales is delighted to announce the engagement of Prince William to Miss Catherine Middleton," the statement from Clarence House early Tuesday read.
Prince William, 28, asked Middleton, also 28, to marry him while the two were on vacation in Kenya last month, the statement said.
The happy couple appeared for the first time after the announcement today arm-in-arm before a barrage of camera flashes, Middleton wearing the famous engagement ring worn by William's mother, the late Princess Diana.
"He's a true romantic and we had a wonderful holiday in Africa and it was out there in a very quiet lodge and it was very romantic and it was very personal time for both of us," said Middleton.
In an interview with Britain's ITV News today, Middleton said the proposal came as a surprise, despite years of public speculation that the couple would wed.
"We were out there with friends, so I really didn't expect it at all," Middleton said. "It was a total shock when it came. Very excited!"
The two met nearly a decade ago while students at the University of St. Andrews in Scotland. The relationship garnered some controversy because Middleton does not come from royalty and royals are generally expected to wed other aristocrats.
William said the two were friends for more than a year and lived as flatmates. "It blossomed from then on," he said. "We had lots of fun. ... Same interests. She has a really naughty sense of humor."
When asked why it took so long to propose, a beaming William quipped, "I also didn't realize it was a race, otherwise I probably would've been a lot quicker."
"We have a great fun time together," the prince told reporters. As for the ring, William said, it, like Kate, was very special to him.
"Well as you may recognize now, it's my mother's engagement ring and it's very special to me, as Kate is very special to me now as well. It was only right the two were put together," William said. "It was my way of making sure mother didn't miss out on today and the excitement and the fact that we're going to spend the rest of our lives together."
Diana received the ring from Prince Charles after the two were engaged in 1981. At the time, the sapphire ring, which is surrounded by 14 diamonds, cost 30,000 pounds.
"I had been carrying it around in my rucksack for about three weeks before [the proposal]," William told ITV. "Everywhere I went, I was keeping ahold of it, cause I knew if this thing disappeared, I'd be in a lot of trouble."
"It's beautiful," Middleton said, as she showed the ring to ITV's camera.
While Middleton is now wearing Diana's ring, William said that she won't be in his mother's shadow.
"There's no pressure," he said. "Like Kate said, it is about carving your own future. No one is trying to fill my mother's shoes. What she did was fantastic. It's about making your own future and your own destiny, and Kate will do a very good job of that."
William said he didn't know where to start when asked why the couple was apparently so loving, but said she makes him laugh. For her part, Kate said William was very supportive of her.
