Reese Witherspoon may have three kids and be in her late thirties, but don't accuse her of having boring mom style! (Cough, Jennifer Garner, cough!)

Reese stepped out to lunch in Brentwood on Wednesday, and the Oscar winner was all smiles when we snapped her getting out of the passenger side of her friend's car. We love that she's always in such a good mood!

So when are we going to see her back on the big screen? Very soon! Her upcoming film, The Devil's Knot, hits theaters on May 9, and it tells the true story of three teenagers, known as the West Memphis Three, who were falsely convicted of killing two 8-year-old boys in Tennessee. Reese plays Pam Hobbs, the mother of victim Stevie Branch, and Colin Firth also stars in the movie as Ronald Lax, a private investigator who represents one of the accused teens.
