Listen to Keith Urban on iHeartRadio

Keith Urban is learning how to be more fearless from his wife, Nicole Kidman.

The singer tells ABC News Radio that his Oscar-winning other-half is "really inspiring as an artist" because of her "fearless" creative choices.

He explains that Kidman not only accepts projects she's interested in, but also "gravitates towards things that she's terrified of." He adds that she often chooses to play certain characters simply because the role is a little uncomfortable. 

Keith is gearing up to release his eighth album Fuse on September 10th. Urban was also recently confirmed to return as a judge on the upcoming season of Fox's "American Idol."
