Justin Timberlake is nothing but overjoyed for being a father for the first time and he couldn't be any happier to be awarded as this year's People Magazine's Sexiest New Dad Alive.

The 34-year-old Sexy Back singer welcomed baby boy Silas Randall with wife Jessica Biel in April.

"I've never slept less and dealt with more poop and been SO excited about it," Timberlake told the magazine about being daddy to the 7-month-old.

The singer-actor-entrepreneur-golfer-and-more also described how being a new father was like in his interview with buddy Jimmy Fallon at The Tonight Show. "It is the most insanely amazing, most beautiful, unbelievable thing that can ever happen to you."

The father and son had even started watching golf together.

"We were watching the PGA championship," Timberlake explained of the photo Fallon showed with the adorable duo. "We're working on his swing already," he joked.

On father's day, the proud first-timer took their photo on Instagram, with Silas wearing an "I [Heart] Dad" onesie. "FLEXIN' on Fathers Day," he wrote. "#HappyFathersDay to ALL of the Dads out there from the newest member of the Daddy Fraternity!! -JT"

So that made him so deserving of the title especially having his 33-year-old wife attesting to that.

"He is doing it all," Biel said in an interview in October. "He is in there; he's in there deep."

Biel also has a lot of "wonderful" things to say about their son.

"He's just a joy. It's an amazing, amazing experience," she told NBC's Today in October.

The first-time mom even revealed her favorite mother-and-son moment - which was "probably the moment when he wakes up from a nap."

"He's sort of looking around and you kind of creep up and look over the crib and he looks up and he goes [Biel lets out a big sighing sound]. Just a gummy mouth, no teeth, just a big smile, happy that you're alive and you're just looking at him. That's probably the most magical." She then added cracking she had to "quickly move on from it because there is a dirty diaper in your palm."
