Reese Witherspoon Shows Baby Bump on "Devil's Knot" Set » Gossip - Proving her hard work-ethic, a very pregnant Reese Witherspoon was spotted on the set of her newest film “Devil’s Knot” in Atlanta, GA on Saturday afternoon (June 30).

The 36-year-old actress donned an outfit that added years to her appearance as she enjoyed a cold beverage before shooting scenes for the movie.

The “Legally Blonde” beauty stars alongside Colin Firth, Mireille Enos, Kevin Durand and Dan DeHaan in the Atom Egoyan directed film, which follows the story of the 1993 murders of three eight-year-old children and the subsequent trials of three teenagers charged with and convicted of the crimes.

It’s based on the novel “Devil’s Knot: The True Story of the West Memphis Three,” and is scheduled to hit theaters some time in 2013.
