What better way to remember and honor Joan Rivers than by looking back at all of her funniest moments from Fashion Police?
Tonight, E! will pay tribute to the late comic legend with a 90-minute Fashion Police: Celebrating Joan episode featuring Joan's daughter Melissa Rivers, Kelly Osbourne, Giuliana Rancic and GeorgeKotsiopoulos.
"For the last four years, this set has been to the funniest, most outrageous voice in comedy," Melissa says in a preview clip from tonight's show. "This chair was the place where a woman spoke the truth about celebrities and fashion and did it in a way that was hilarious and absolutely, one hundred percent original. Tonight we want to say goodbye the only way my mom would want us to, by remembering the incredible jokes, the unbelievable guests and all the moments on set and behind the scenes that made Fashion Police must-see television around the globe."

Melissa also relives some of Joan's most hilarious moments from past FP episodes. "I have so many memories on this set of my mom. But honestly, nothing made me smile more than when she would crack herself up before she even got to the punch line of a joke," Melissa tells Giuliana, Kelly and George.

Melissa and the Fashion Police co-hosts also look back on Joan's impact on the world of comedy.
"She affected so many people and people you would never expect to have humor," Melissa says. "I received a letter from the White House from President Obama, someone who was often a target of her jokes, as was Mrs. Obama, but I received a hand-written note saying not only did she make us laugh, she made us think."
