Prince William gushes about Kate Middleton!

Prince William opened up about his married life with wife Kate Middleton, and acknowledged his "struggles" with parenthood in a rare interview on a Vietnamese talk show.

Duke of Cambridge, who is on a two-day visit to the country to fight illegal wildlife trade, appeared on the English-language show Talk Vietnam and admitted "there's wonderful highs and wonderful lows" when it comes to parenting.

He also praised his wife Catherine, and said [via People Magazine], "It's been quite a change for me personally. I'm very lucky in the support I have from Catherine, she's an amazing mother and a fantastic wife."

The 34-year-old Royal admitted that having children is life changing. He said "I've struggled at times. The alteration from being a single, independent man to going into marriage and then having children is life-changing. I adore my children very much, and I've learned a lot about myself and about family just from having my own children."

Calling 3-year-old son Prince George "a right little rascal," William said, "He keeps me on my toes but he's a sweet boy." The Duke also spoke about his 18-month-old daughter Princess Charlotte, and said, "Bearing in mind I haven't had a sister, so having a daughter is a very different dynamic. So I'm learning about having a daughter, having a girl in the family."

The Prince shared his advice on protecting wildlife and how to make a difference to the audience. He explained, "When you have something or someone in your life to give the future to, I think it focuses the mind more about what you're giving them. Are you happy that you've done all you can to leave it in a good state?"

"I would like [my kids] to grow up with more simple aspirations. I think there's a lot of huge aspirations and people living with an enormous amount of stuff that they don't necessarily need," he added.

The Royal concluded by saying, "I would like George and Charlotte to grow up being a little bit more simple in their approach and their outlook, and just looking after those around them and treating others as they would like to be treated themselves."
