Looks like Reese Witherspoon spent her summer slimming down! The 37-year-old actress looked hotter than ever at the premiere of her latest film, Devil's Knot, at the 2013 Toronto International Film Festival on Sunday, Sept. 8. The mother of three -- Ava, 13, Deacon, 9, and Tennessee, 11 months -- showed off her stunning body on the red carpet at The Elgin in Toronto, Canada.
Witherspoon showcased her skinny and toned figure in a black and white Jason Wu dress that exposed some cleavage with a sexy cut-out neckline. Wearing her blonde curly hair swept to the side, Witherspoon accessorized her glam look with Jimmy Choo shoes and Tiffany & Co. jewelry. (She later shined at Worldview's party to celebrate all six of their films at the festival -- including Devil's Knot -- hosted by SodaStream and held at the Live at the Hive pop up.)
The actress filmed Devil's Knot while she was pregnant with Tennessee, her first child with husband Jim Toth. (Witherspoon shares custody of daughter Ava and son Deacon with ex-husband Ryan Phillippe.) She was photographed on the set in June 2012, proudly showing her big baby bump.
Based on the 2002 best-seller by Mara Leveritt, Devil's Knot, also starring Colin Firth, tells the story about three teenagers falsely convicted of killing three 8-year-old boys during a satanic ritual. The defendants, called the West Memphis 3, were freed in August 2011 after spending 18 years in jail.
