Nick Jonas, John MulaneyAnd Sam Hunt all have one major thing in common: They’re about to celebrate their first Father’s Day as a dad this year.

Although raising a child is a new experience for many A-list parents and celebrities, they are not afraid to share their fatherhood experiences with fans.

“I just had a baby boy named after me.” Lucy LuSam’s wife had their daughter June in June and he said that during a recent concert. “I think being out here, and in the music business and being out on the road, has sort of hardened my heart. My heart’s definitely a lot harder in a lotta ways since I left that small town. Amazing how this little girl took all that away in a matter of hours a few weeks back.

Sam isn’t alone in being touched by fatherhood.
