Reese Witherspoon gave birth to son Tennessee James Toth today, her rep confirms to 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 rep said in a statement.

The little boy joins big sister Ava, 13, and brother Deacon, 8, from the Oscar winner's first marriage to Ryan Phillippe.

This is the first biological child for the couple, who married at the actress' Ojai Valley estate in March 2011.

Congrats to the happy family!
