Meet Tennessee James Toth! Reese Witherspoon gave the world a peek at her 6-week-old son while out and about in California on November 7.

The actress’s third child — her first with husband Jim Toth — arrived Sept. 27 in Santa Monica, her rep told WHO exclusively at the time.

Although Witherspoon, 36, has stepped out solo since the arrival of her baby boy, this is the first time she’s been spotted with her new son.

“Everyone is bonding with the baby,” a source tells WHO of the relationship Witherspoon’s elder children — Deacon, 9, and Ava, 13 — have with their new little brother. “And Jim has had a lighter workload and has been spending a lot of time at home with the baby as well.”

Adds a Witherspoon pal: “She’s so content. Tennessee is a great little guy and he’s fitting right into their family"

"Jim’s been incredibly supportive, pitching in with Ava and Deacon and generally just being someone for Reese to lean on. They’re all very happy.”

Toth has also stepped up in his role as stepfather to Witherspoon's two children with ex-husband Ryan Philippe, who sources say bonded easily with Toth early on in his relationship with their mum.

"He's a grownup who's really ready to take the next step," a Witherspoon source told WHO about Toth when the pair got engaged in 2010. "He's a family-oriented guy, and that's all she ever really wanted."
