OH BOY!
This may go down as the most rim-shakin' gender reveal of all time!!!
NBA guard Austin Rivers and his model girlfriend, Audreyana Michelle, got extra creative when revealing the gender of their baby ... by lobbing a ball to daddy -- and it poofed into a cloud of blue!!
The stunning Audreyana announced the baby on the way just days ago ... with a mirror selfie captioned, "social distancing failed."
Austin got in on the fun, too, saying, "Pretty much lol. Love you babyu2764ufe0f"
Now, we know the newcomer is a baby boy .
