If that bump could talk!

Reese Witherspoon has yet to publicly confirm that she's pregnant with her third child. But on Tuesday, the 36-year-old Oscar winner continued to go about her business near her home in L.A.'s Brentwood area, and showed off her effortless chic maternity style -- and a noticeably larger bump!

Expecting her first child with hubby Jim Toth, the This Means Wear star wore a clingy maroon dress that accentuated her expanding tummy, paired with a leather jacket, beaded necklace and strappy sandals.

Us Weekly was first to break news that the A-list actress was expecting again, and an insider said Witherspoon would "just let people figure it out."

Witherspoon and CAA agent Toth 41, celebrated their one-year wedding anniversary, their baby news and the Easter holiday in Costa Rica with Ava, 12, and Deacon, 8, her kids with ex Ryan Phillippe, where she similarly flaunted her bump in a swimsuit. The star "is confident about her body," a source told Us Weekly. "Reese is really excited to be pregnant again!"
