Keith Urban and Dierks Bentley shared some sweet sentiments about their wives in honor of Mother’s Day on May 13.

Dierks Bentley & Cassidy

Dierks married wife Cassidy Black in 2005, and they have two daughters, Evelyn Day, 9, and Jordan Catherine, 7, and one son, Knox, 4.

“It’s the toughest job out there being a mom, and I know from my life with my wife Cassidy. We work as a team together when I’m home, and it takes everyone to get the job done, me and her, working together. So, when I go on the road, I just have so much respect for her because it’s hard to do it right, if you want to do it great, and she does a great job with it. It’s really rewarding, but it’s also very challenging. I’m so thankful that she takes it on the way she does, and our kids are very lucky to have her.”

Keith Urban & Nicole Kidman

Keith married wife Nicole Kidman in 2006, and they have two daughters, Sunday Rose, 9, and Faith Margaret, 7.

“She’s an extraordinary mum, she really, really is. Those girls are very, very lucky, and I feel very lucky that the children I should have in this world happen to be with Nic. I don’t know anything about raising kids and Nic does, and that comes in extremely, um, it’s really made for an experience I wouldn’t have had without that. Her patience, her recognizing them as people and not just little kids is really extraordinary. Her attention to honoring their feelings and listening to them right from day one – really being attentive to that is not how I was raised at all, so it’s really beautiful to see.”
