John Legend has been changed by fatherhood.

The 'All Of Me' hitmaker says he has a newfound understanding of "how fragile life can be sometimes" after welcoming his daughter Luna into the world 20 months ago.

Speaking to accept the Visionary award at the Art of Elysium's Heaven Celebration in Santa Monica, California over the weekend, John said: "I think being a father helps me understand even more how fragile life can be sometimes and how much it's imperative for us who have so many resources and so much power to try to make other kids' lives better.

"Because we know we can afford for our kids to have proper health care, to have proper education, but there are so many kids in our country and around the world who don't have that and I think this experience of fatherhood has made me double down on saying, we got to do what we can together to make this world better for our young people growing up."

Meanwhile, a source previously revealed that John and his wife Chrissy Teigen - who are expecting their second child together - are "so excited" that their daughter Luna is going to be a big sister.

The insider shared: "They have been planning for this for a long time. Chrissy is really excited to finally share the news. They are so excited to make Luna a big sister. They think Luna will do a great job with the baby and they're really happy to be expanding their family."
