Reynolds, 84, passed away on Dec. 28 at Cedars-Sinai Medical Center in Los Angeles, just one day after her 60-year-old daughter, Carrie Fisher, died from a massive heart attack.
The mother-daughter duo recently starred together in the HBO documentary "Bright Lights," which premiered at Cannes back in May. Directed by Fisher Stevens and Alexis Bloom, the doc looked back on the pair's relationship through the years, as well as their equally monumental legacies in Hollywood.
