The actress posted a picture of a Buddha sitting peacefully underneath a tree on Tuesday, shortly after news broke that she had welcomed a baby boy with husband Brian Austin Green.
Upon closer inspection, the illustration features a Bodhi tree and that's what the couple reportedly named their son: Bodhi Ransom Green.
Before this post, Fox had been pretty quiet on the social media front in recent weeks.
The Teenage Mutant Ninja Turtles star and the Beverly Hills 90210 alum welcomed their second child, another baby boy, People reported Thursday.
Their new addition joins brother Noah, 16 months, in the family fold. Green is also dad to 11-year-old son Kassius from a previous relationship.
The couple was married in June 2010.
The actress' rep confirmed in August that the couple were "very happy" to be expecting again.
TMZ reported the name of the baby boy.
Congrats again to the family!
