Daddy doody! Justin Timberlake shared poop stories to describe first-time fatherhood in a hilarious Friday, May 6, interview with Elvis Duran on New York City’s Z100 morning radio show.

“Oh, you look at everything differently now! Yes, having a little man in the house now changes everything!” the pop star, 35, said of being a dad to son Silas, 13 months, who he shares with wife Jessica Biel. “When I used to clean up my dog’s poop, it was like it was a science project; I wouldn’t get very close to it. When you have a kid, and there’s poop, you gotta get in there!”

“Nothing trumps your kid’s butt cleanliness,” the “Can’t Stop the Feeling!” crooner added. “So you just have to get in there!”

Timberlake and Biel tied the knot in a romantic October 2012 wedding ceremony in Italy. Us Weekly broke the news of Biel’s pregnancy in late 2014, and Silas was born in April 2015.

For Father's Day 2015, Timberlake posted an adorable Instagram of himself and his little guy. "FLEXIN' on Fathers Day...," he wrote alongside the sweet snapshot. "#HappyFathersDay to ALL of the Dads out there from the newest member of the Daddy Fraternity!! --JT."

Back in October, Biel, 34, gushed on the Today show that Silas is “wonderful. He’s just a joy. [Motherhood is] an amazing, amazing experience.”

"[It's] incredibly hard, the hardest job in the world, and I've never been more thankful and grateful to my own mother," the 7th Heaven alum said. "Oh, my gosh. I'm going to call her right after this actually and just thank her. What you have to do for your kid — it's an amazing responsibility and the biggest joy ever."
