The May December actor is now more of a March guy since welcoming a daughter with music video director Camille Summers-Valli.
Becoming a dad was “the best thing,” Melton said, but, as he told Men’s Health, “I never knew if that dream was going to happen, because you’ve got to meet the right person. And I did.”

The Love Story: John F. Kennedy Jr. & Carolyn Bessette actor is over the moon since welcoming a baby with wife Syd Widziszewski-Kelly in February.
“Bcoming a father during this crazy whirlwind [time] is definitely not without its challenges,” Kelly, an overnight sensation thanks to his turn as JFK Jr., told People in April. “But the moment I’m home, I’m just present and in dad mode and changing diapers and cleaning up puke and all the good stuff that comes along with it. But it is the most magical experience, and I couldn’t be happier.”

The How I Met Your Mother alum introduced the world to his and Jordana Jacobs‘ son in February, writing, “So my wife and I had a baby a few months ago (!!) Here’s what we know so far: His smile lights up the room. He’s super observant and thoughtful. He gets hypnotized when I play him songs on the guitar. He thinks the word ‘baba ghanoush’ is hysterical…Sending love to all my fellow parents of newborns out there. What a wild, beautiful, exhausting, heart-opening initiation.”
