David Beckham on Building a New 'Legacy' Project for His Kids (Exclusive)

"I like to feel that I still impress my kids all the time," the father of four told ET.

David Beckham's new business venture is a family affair.

For the iconic soccer star's latest project, he's now co-owner of a new Major League Soccer team, Inter Miami. Beckham says the long-term goal is to leave a legacy for his four kids -- Brooklyn, 20, Romeo, 17, Cruz, 15, and Harper, 8.

ET's Rachel Smith spoke with the 44-year-old former soccer pro in New York City on Wednesday, where he explained, "I like to feel that I still impress my kids all the time."

"We've always said that this is not a vanity project for us. This is a legacy. It is what we want to create for our children. We want our children to turn around in 10, 15, 20 years and say, 'Our dads built this,'" Beckham says of him and his co-owners, Marcelo Claure, Jorge Mas and Masayoshi Son.

"We wanna make our families proud of creating something for them, for the future, and for the people of Miami and South Florida," he added.

As for how the team has impacted his own life, Beckham found it to be a good way to remain involved in the sport, which he retired from in 2013. "I'm so thankful to have had the long career that I have had," he says. "But now to be able to go into the business side -- being owner of a team, being owner of my own business -- that, for me, is an incredible journey and I'm just enjoying it."

Beckham might also enjoy it with a few of his famous friends -- for example, Prince Harry and Meghan Markle, who Beckham said are "all invited" to attend a game at the Fort Lauderdale stadium.

In fact, Beckham praised Prince Harry amid the royal's relocation to Canada with his wife and their 9-month-old son, Archie.

"I haven't spoken to Harry about him moving. We speak as friends and that's the most important thing for me," Beckham says. "I think he's enjoying being a young father for the first time and that's what we always spoke about. When you are a parent, it changes everything for you. He always needs to be happy."

Beckham went on to say that he and his wife, Victoria, with whom he attended Harry and Meghan's wedding in 2018, are proud of how Harry's adapted to fatherhood.

"We love him and he's an amazing person -- and that's the most important thing -- but I'm proud to see him growing up as an individual and being that person that every father wants to be," Beckham says. "Every father wants to be loving to their children and that's what I see with him."
