"We had a little private time away together with some friends and I just decided that it was the right time really. We had been talking about marriage for a while so it wasn't a massively big surprise. I took her up somewhere nice in Kenya and I proposed," William said.
"It was supposed to be a small family affair," Prince William joked to father-in-law Michael Middleton as he gave his daughter away.
"She's got a really naughty sense of humour, which kind of helps me because I've got a really dry sense of humour," the Duke of Cambridge pointed out.
"Catherine and I are clear that we want both George and Charlotte to grow up feeling able to talk about their emotions and feelings," the Prince once told CALMzine.
"I've talked about going to Glastonbury before because I do love my music and Catherine as well. I've got into enough trouble with my dancing recently. So it's probably best to stay away from that one," William joked on Radio 1.
Although they don't watch The Crown, the couple love bingeing on box sets like Game Of Thrones and Homeland "once the kiddies are in bed."
"We obviously met at university - at St Andrews we were friends for over a year first and it just sort of blossomed from then on. We just spent more time with each other had a good giggle, had lots of fun and realised we shared the same interests and just had a really good time," Wills reflected.
"I think at the time I wasn't very happy about it, but actually it made me a stronger person, you find out things about yourself that maybe you hadn't realised, I think you can get quite consumed by a relationship when you are younger and I really valued that time for me as well although I didn't think it at the time," the mother-of-two has confessed.
"When I first met Kate I knew there was something very special about her. I knew there was possibly something that I wanted to explore there. But we ended up being friends for a while and that was a good foundation," Wills has gushed.
