Reese Witherspoon hit the red carpet in a sexy Jason Wu dress for the Toronto International Film Festival premiere of Devil's Knot on Sunday. She was joined by her costar Colin Firth to promote the crime drama, which is based on the real-life story of three teenagers known as the West Memphis Three. The teens were accused of killing three young boys as part of a satanic ritual in 1993, and Reese stars as the mother of one of the suspected murderers.
Reese touched down in Toronto earlier in the day to fulfill her film festival duties. She jetted up to Canada after spending the weekend with her daughter, Ava Phillippe, and young son Tennessee Toth, who is turning 1 later this month. The blond trio took a trip to The Brentwood Country Mart for shopping and lunch, and Ava showed off her big-sister skills by carrying her baby brother down the street.
