Meet Ne-Yo's 4 Adorable Kids — Before He Welcomes Baby Number 5!

Also known as SJ, Shaffer Chimere Smith Jr. was born March 15, 2016. He's Ne-Yo's third child and the first with his wife, Crystal Williams. As the "junior" in his name suggests, SJ actually shares his father's real name!

One of Ne-Yo's recent collaborations, a music video for "Shake" for which he partnered with Lego, was created out of a desire to do more things he could share with his children. "When they gave me a call and asked me about it, I was instantly in because my kids are huge LEGO fans and have been for forever," he told People. He added: "It does get kind of hard to find stuff that I can do that I can include them in as well. That's why when this came through, I was in before they even really told me what it was."
