Tennessee James Toth: Reese Witherspoon, Jim Toth Welcome Baby Boy

It's a boy for Reese Witherspoon and Jim Toth! The couple welcomed their first child together on Sept. 27, her rep confirms to People.

“Reese Witherspoon and husband Jim Toth welcomed Tennessee James into their family today,” the rep says. “Both mom and baby are healthy and the entire family is thrilled.”

The new addition to the Witherspoon-Toth family joins big sister Ava, 13, and her little brother Deacon, 8, Witherspoon's children with ex-husband Ryan Phillippe. This is the first child for Toth.

Witherspoon, 36, and Toth, who married in March 2011, have been fairly private throughout the pregnancy. Sources spilled the baby beans in March, revealing to Us Weekly that Witherspoon was expecting her third child. It wasn't long until photos of the star sporting a prominent baby bump started making the rounds, but the couple stayed mum about the news.

The actress finally made mention of her pregnancy in June, when she attended a Chicago event.

"Thanks, but frankly I’m feeling very round tonight," she told the Chicago Sun-Times when complimented on her look.

Congratulations to the happy family!
