Keith Urban is speaking out about his late father.

In a surprise appearance on Wednesday's The Ellen DeGeneres Show, the 48-year-old recalls how his dad sparked his love of country music.

"Our record collection was all American country music," the Aussie said, "and that's what really pointed me in the direction of Nashville."

The singer's father, Robert Urban, died Dec. 5 after a long battle with cancer.

"I've been deeply touched by the outpouring of love and support that [wife Nicole Kidman] and I, and our family, have received since my Dad's passing on Saturday night," Urban shared in a statement at the time. "His long battle with cancer is now over and he is finally at peace. My Dad’s love of country music and America set me on my life's journey, and shaped so much of who I am today. Thank you to everyone who has kept us all in your thoughts and prayers."

But as Urban continues to mourn the loss of his father, he's also back to work promoting the final season of American Idol and his upcoming RipCORD World Tour.

"We'll be playing a lot of new music from RipCORD, all new production, new cities where we've never played … and Brett Eldredge and Maren Morris? It's gonna be potent and unbridled!!!" Urban gushed in announcing the tour. See a complete list of tour dates here.

RipCORD, the album, has not yet been released, but has already produced two hit singles: "John Cougar, John Deere, John 3:16" and "Break On Me."

Back in 2014, Urban's wife was seated in the DeGeneres hot seat and couldn't help spilling sweet details about the couple’s relationship. See Kidman's interview below.
