Reese Witherspoon gave birth to her third child, son Tennessee, in September. Making an appearance on Chelsea Lately, Reese spoke about her son’s name, her holiday party and much more!!

Chelsea asked Reese an interesting question, “How did you get pregnant?” which resulted in giggles and a response of “how do you think I got pregnant?” Chelsea must be running out of material? Why else would she ask that question?

The name Tennessee has sentimental value for Reese since that is where she is originally from.

Reese has two other children from her first marriage to actor Ryan Phillippe, Deacon, eight, and Ava, whom Reese says is a huge help when it comes to caring for the newborn. ‘She’s 13 and so awesome,’ the actress stated.

Reese isn’t the only celebrity to have a baby in 2012. She joins Snooki, Jessica Simpson, Megan Fox and many more famous women in giving birth this year.
