On Friday, September 19th, E! is celebrating the laughter that Joan brought to viewers around the world with “Joan Day.” Programming will include an all-day marathon that showcases some of Joan’s best jokes from “Fashion Police” beginning at 7:00am ET/PT. Hilarious back-to-back episodes, including Joan’s milestone 80th birthday celebration and the last “Fashion Police” she did for the MTV Video Music Awards and Primetime Emmy special, highlight some of Joan’s laugh-out-loud funniest and most outrageous moments from her past four years on the series.

Then the “Fashion Police” family honors Joan with a touching and hilarious 90-minute on-air celebration befitting of the woman whose sharp wit and biting comedy made her a legend to millions of fans, and who changed forever the face of Red Carpet fashion commentary. Melissa Rivers (also executive producer of “Fashion Police”) will join her onscreen “family” Kelly Osbourne, Giuliana Rancic, and George Kotsiopoulos, as they lovingly and, of course, laughingly, pay tribute to Joan’s years as the host of “Fashion Police” when “Fashion Police: Celebrating Joan” airs at 8:00pm ET/PT.

The special will feature behind-the-scenes footage, including never-before-aired moments of Joan candidly joking with the cast and cracking up the studio audience, along with outtakes featuring Joan doing what she did best — making everyone within earshot of her laugh. With no shortage of funny moments from which to choose, this tribute will feature some of the best of Joan’s trademark “did she really just say that” remarks and outlandish stunts, along with clips of some of the incredible guests from the worlds of fashion, entertainment, sports and more that joined Joan on the “Fashion Police” stage. Personal stories from the co-hosts and Melissa will round out this special to celebrate the gift of laughter Joan so freely shared with fans and “Joan Rangers” around the world.

Join E! tomorrow for a full day of laughter commemorating Joan!
