Friday will mark the one-year anniversary of Joan's death due to complications from a surgical procedure. She was 81.
"Coop (brother Cooper) and I took our annual family vacation to Wyoming. (The) first without my mom and scattered some of her ashes there so we can still be together every August as a family."
Melissa, who stepped into her mom's role as host of E!'s "Fashion Police" when it returned to the air on Monday, plans to mark the anniversary of her mother's death in a very low-key way, reported People magazine.
"Cooper and I talk about what would be the best way to honour her legacy and the best way to honour her legacy is to be okay," Melissa, 47, said.
