The So Sick hitmaker and his wife, Crystal Renay, welcomed their first child together, son Shaffer Chimere Smith, Jr., on 16 March (16), and Ne-Yo admits new fatherhood is everything he remembers it to be.

The singer, who also has two children from a previous relationship, reveals his baby boy, nicknamed Prince SJ, is a relatively quiet kid, but he doesn't like to sleep.

"I haven't slept in about 14 days," he told People.com as he enjoyed a night out on Wednesday (27Apr16) at the 33rd Annual ASCAP Pop Awards in Los Angeles. "I'm loving every minute of it."

"He's actually a really good baby," Ne-Yo continued. "He doesn't cry much, he just doesn't sleep at all. So if he's awake, I gotta be awake, so that's how that goes."

Proud dad Ne-Yo is also enjoying watching his son develop various facial expressions: "He does a lot of side-eyeing," the singer smiled. "Looking out of the corner of his eyes like, 'What are you doing?' He does a lot of that. No words or anything."

However, Prince SJ is already showing an interest in music, especially his father's.

"He responds to the more up-tempo stuff," Ne-Yo explained. "I got a pop baby, he likes the pop stuff."

Revealing the newborn's favourite song is dad's Pitbull collaboration Time of Our Lives, the 36-year-old added, "He likes the guitars, oddly enough. That's when he would move the most."

Meanwhile, Ne-Yo, real name Shaffer Chimere Smith, claims his wife has already bounced back from giving birth via emergency Caesarean section.

"She's doing fantastic. She's completely recovered," he shared. "She's loving being a mum and everything at home, but she's ready to get back out there and contribute."
