Today marks the one-year anniversary of Joan Rivers' tragic passing, and the tributes are pouring in for the legendary comedienne.
Daughter Melissa Riversposted a touching message for Joan on the late star's Twitter page and admits life's "been difficult" since she lost her mom.
"Today marks one year since my mother passed. This was the year of firsts: first holidays, first birthdays, first everythings without mom, without grandma," the 47-year-old star, whose 14-year-old son Cooper was incredibly close to his grandmother, wrote.
