pregnant

With her third child on the way, Reese Witherspoon is a mama on a mission!

The Oscar-winning actress, who's expecting her little bundle with new hubby Jim Toth this year, hit up the Country Mart in Brentwood wearing a casual-yet-clingy purple dress, a brown leather jacket and matching sandals.

No doubt about it, that's a baby bump we see ... even though the Water for Elephants star has yet to confirm her pregnancy.

We have a feeling Reese's daughter Ava and son Deacon are counting down the days until their little sibling arrives!
