Reese Witherspoon is once again a new mom -- she just gave birth to a baby boy!

Reese, 36, and husband Jim Toth, 41, welcomed Tennessee James early Thursday.

A rep tells PEOPLE "Reese Witherspoon and husband Jim Toth welcomed Tennessee James into their family today. Both mom and baby are healthy and the entire family is thrilled."

The new addition is the first child for the couple, who have been married since March of last year.

Reese already has daughter Ava, 12, and son Deacon, 8, from her previous marriage to Ryan Phillippe.

Congratulations to the happy family!
