Reese Witherspoon Welcomes Son Tennessee James

In March, a source told PEOPLE that the actress, 36, was eager to have another child. "Right after the wedding, Reese expressed a desire to have a baby with Jim," said the source. "Reese has been very open with her kids about her plans to expand the family."

Witherspoon, who initially kept her pregnancy under wraps, subsequently showed off her baby bump all around the world over the spring and summer — from appearances at the Cannes Film Festival to lunches and errands at home in Los Angeles. "Frankly, I'm feeling very round," she told reporters in June.
