Even within her inner circle, Reese Witherspoon remained tight-lipped about her third pregnancy.
"Umm . . . " Witherspoon replied, giggling. "I don't know. How do you think I got pregnant? Do you want to talk about this later? We don't have to talk about it right now."
Without missing a beat, Handler replied, "We don't have to talk about it now -- but I would prefer to!"
At one point, Handler added, Witherspoon nearly spilled the beans via text message. "Then you said, 'I'm pretty sure someone's reading our texts,' and I said, 'Please don't text me again because I don't want to be blamed," the Are You There, Vodka? It's Me, Chelsea author recalled. "Then you had the baby and you named it Tennessee and I still couldn't figure out if it was a boy or a girl."
Witherspoon laughed loudly and added, "Or just a redneck!"
Calling her newborn son "super cute," Witherspoon praised her daughter, Ava, for being a hands-on big sister: "She's 13 and so awesome!"
Witherspoon and her husband, CAA agent Jim Toth, 41, welcomed Tennessee Sept. 27. The Devil's Knot actress is also mom to son Deacon, 8, from her marriage to Ryan Phillippe.
