He may be less than a week old, but Ne-Yo and Crystal Renay's baby boy has already stolen our hearts!

The About The Business star, who also goes by Crystal Williams, shared a new snap of  her first child with husband Ne-Yo to Instagram on Thursday, writing, "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," the proud mama added. "Love you to the moon and back daddy!"

And, proving that you're never too little for a throwback, Crystal posted a video of her pride and joy to Instagram, explaining why it was mistime-stamped as 1986, which predates little Shaffer by a good 30 years.

"He was only 6 hrs and 11 mins old and already my heart was stolen ? All I can say is LOVE! @neyo Now life really begins and I couldn't be happier about it! ******** P.s He wasn't born in 86 lol it's a app and I was too excited using it the first time with him to change the year but hey I'm a 86 baby so go head and rep for me son," Crystal captioned the video.
