Joan Rivers Mourned By 'Fashion Police' Melissa Rivers, Kelly Osbourne, And Kathy Griffin [Video]

For Melissa Rivers and her son Cooper, healing from the grief that accompanies the loss of a parent and beloved grandparent like Joan Rivers is taking many forms. Because Joan was known for her humor, however, Melissa has one special wish for her 13-year-old son. And that's to help him heal through laughter, reported People magazine.

Cooper adored his grandmother,who he dubbed Nana New Face. He appeared with Melissa and Joan on the Joan & Melissa: Joan Knows Best? reality show.

Prior to her death, Joan revealed that her grandson's sense of humor caused them to bond.

"[Cooper has] a great sense of humor. I don't know if it's mine but that was how we first connected."

But Cooper and Melissa aren't alone in continuing to mourn Joan's passing. Kelly Osbourne, who co-starred on Fashion Police with the comedienne, is anxious about continuing the show without Rivers, she told Us Weekly.

Asked to pay tribute to her memory of Joan on the show, Kelly couldn't control her tears, as shown below.

I'm excited but terrified at the same time. Change isn't fun, but it has to happen. This sitution f**king sucks.
The changes planned for Fashion Police include more mourning Joan. Kathy Griffin, who was a close friend of Joan's, will replace her. Completing the game of musical co-stars chairs, stylist Brad Goreski will take over for the exiting George Kotsiopoulos. And viewers can look for Melissa Rivers to continue her role as Executive Producer.

As for the format, Fashion Police no longer will air weekly. Instead, the co-hosts will focus on 17 episodes in 2015 that are scheduled to feature red carpet events such as the Emmy Awards and Oscars ceremony.

To those who are perturbed that Kathy will take over for Joan, Griffin emphasizes that the two had joked about the possibility, and thus she feels that Rivers would love the fact that she's taking this opportunity to critique the rich and famous just like Joan. She even strutted her fashionista sensibility by providing Jimmy Kimmel with tips, below.

Joan and I talked about it many times, and she joked that no matter what, I should always get 10 percent less than she got.

I've been a fashion 'don't' for years! I used to laminate my 'What was she thinking?' pictures and put them on my refrigerator, but then they covered the entire wall. I'm not afraid to be a do or a don't; I'm not afraid of a wrong moment, because that's what fashion should be. Take some chances!

For Melissa, remembering Joan means more than managing Fashion Police. As the Inquisitr reported, she chose to celebrate her first Thanksgiving without her mother by honoring her memory with a dinner that included the same close friends and family who had regularly attended.

"Joan would welcome her friends, relatives and anyone who might not have family members in New York to a Thanksgiving dinner at her home," recalled a source.

Reigning at the table of 50, Joan would require each guest to reveal what he or she was thankful for. Although Melissa recognized that it might open the door to grieving her loss, she wanted to continue that legacy to honor her mother, said the source.
