OMG! What a cutie! Ne-Yo's wife, Crystal Renay, shared the most adorable photograph ever of their newborn son Shaffer Chimere Smith Jr. on Thursday, March 17 — and he's totally gorgeous.

The photograph, which also announced the newborn baby's full name, shows the alert little guy resting on mom's chest while still in the hospital.

"Allow me to introduce to you all Shaffer Chimere Smith Jr! I AM SO IN LOVE WITH THIS LIL MAN! Now I know what it means to have your heart walk around outside of your body...THANK YOU @neyo for the greatest gift in the world! Love you to the moon and back daddy! #HeIsPERFECT," an elated Renay captioned the supercute snap.

Daddy Ne-Yo also shared a new black and white photograph of his precious little guy, showing the pair of them cuddled up shortly after the birth, with the words "senior" and "junior" superimposed on the pic.

The R&B star, who already has two kids, Madilyn Grace, 5, and Mason Evan, 4, with his ex, Monyetta Shaw, welcomed his newest arrival into the family with his caption.

"Welcome to the world lil' man. (HA! Mason's a big brother now) You got a BIG family lookin' out for you, immediate AND extended. And we all love you to death. Gonna do EVERYTHING in my power to make sure ALL my children never need for anything EVER. @iamcrystalrenay I love you lovely. Thank you for this amazing gift!"

As Us Weekly reported previously, the couple, who married in California last month, welcomed little Shaffer into the world on Wednesday, March 16.
