“I have always been the youngest sibling, from being pushed on the swings by Will and Nash, to being forced to sit in the middle because I was the smallest,” he wrote on Instagram. “It’s just how it goes being the youngest. And now, I’m an older brother and an uncle. So it’s my turn. And I can’t wait.”

Nash tweeted, “I’M AN UNCLE”

Congrats to the entire Grier family on the new addition!
