Reese Witherspoon (muumuu clad!) takes son Deacon to work

It's a muumuu!

Pregnant Reese Witherspoon, 36, took her son Deacon, 8.5, with her to the set of her latest crime film, Devil's Knot, in Atlanta, Georgia, earlier this week. Deacon seemed thrilled to be on the set, and so happy to be with mom.

Indeed, while Deacon looked dapper in his LA Dodgers hat, Reese wasn't her usual stylish self in that short denim muumuu! BUT, I'm guessing she was in character. Her hair was looking a little lacklustre, too, so definitely in character.

Still..., she's adorable.

This is the last film Reese is doing before baby arrives in the fall, and it's due to wrap up soon!

LOVE!
