India, Aug. 8 -- Jane Etta Pitt, the mother of actor Brad Pitt, died at the age of 84. Sources close to the Pitt family told TMZ that Jane passed away "in the last day or two," while one of her granddaughters, Sydney Pitt, paid a tribute to her on Instagram. Sydney, who is Brad Pitt's niece and the daughter of his brother Doug Pitt, posted a heartfelt message on Instagram on August 6. "My sweet Grammy, Jane Etta, we were not ready for you to go yet, but knowing you are finally free to sing, dance, and paint again makes it a tad easier," she wrote. Jane, a retired school counsellor, raised Brad and his two younger siblings, Doug and Julie, in Missouri's Springfield, along with her husband William, who earlier was the owner of a trucking company, according to People magazine. While Jane and her husband mostly remained away from the limelight, they were occasionally seen alongside the actor at a few events, which included the 2012 Oscars as well as the 2014 premiere of Unbroken, which featured Brad Pitt's former wife Angelina Jolie. Besides this, Jane was even present during the 1997 premiere of The Devil's Own, where they were joined by Gwyneth Paltrow. HTC...
