Reese Witherspoon introduced her newborn boy, Tennessee James Toth, to the world on Wednesday.

The actress, 36, dressed down in a denim shirt and jeans as she pushed her 6-week-old son in a stroller around Los Angeles. This is the first time Witherspoon has been spotted with her newborn.

Tennessee is Witherspoon's third child and her first with husband Jim Toth. Toth, 41, a Hollywood agent, wed Witherspoon in March 2011 after a year of dating.

Witherspoon has two children, Ava, 13, and Deacon, 9, with her ex-husband, actor Ryan Phillippe. The two, who share custody of their kids, split in 2006 after seven years of marriage.
