Joan Rivers' "Fashion Police" show on E! may not be coming back following the death of its popular host, reports said even as the network planned to air a special 90-minute tribute to Rivers Friday night. E! called Friday "Joan Day" in remembrance of the star.

Giuliana Rancic, who co-hosted the show starting with its 2010 debut along with Rivers and Kelly Osbourne, said producers along with the show's executive producer, Melissa Rivers, daughter of the deceased comic, and E! officials were holding discussions about the future of the show dedicated, as the name implied, to policing celebrity fashion.

Osbourne and the fourth host, George Kotsiopoulos, said they hadn't taken part in those discussions and said they didn't know anything about the show's future.

E! held a day-long marathon of "Fashion Police" episodes building up to its Friday night tribute show titled "Celebrating Joan." The special tribute included the remaining show hosts who they referred to as Joan Rivers' "on-screen family" and Melissa Rivers. The show was a tribute to Rivers' capacity for reinvention, producers said.

Melissa Rivers made her first public appearance since her mother's death on Friday's edition of ABC TV's "Good Morning America." She said she was overwhelmed by the outpouring of support for her mother.

Revealed through preview tapes of Friday's tribute to Joan Rivers on E! was the information that Michelle Obama sent a hand-written note to Melissa Rivers saying Joan Rivers was an icon who made everybody laugh and think.

As for the show's future, Rancic said producers were looking at "different scenarios,"adding the show's future depended on many factors with foremost being how Melissa Rivers felt about it continuing. Producers were considering how the show might look without the comedienne, Rancic said.

Rancic added that a part of her wanted the show to continue as a tribute to Rivers, but it was a matter of whether they could go on with the show without its leading lady and shining light.
