REESE WITHERSOON has given birth to a new son.

The Oscar winner gave birth earlier today to son Tennessee James Toth.

Tennessee is Reese’s first child with agent hubby Jim Toth.  The new babe joins older sister Ava, 13, and Deacon, 8, whose dad is her ex-husband Ryan Phillippe.  

Reese has spoken about expanding her family previously, saying “My children are the best part of my day.”

“Both mom and baby are healthy and the entire family is thrilled,” their rep confirmed 

If you’re wondering where Reese got the name Tennessee, she spent most of her childhood there, reported.

Sorry Alabama.

You’re just not Reese’s sweet home, after all.
