Joan Rivers, the late comedienne who interviewed countless A-listers at the Oscars over the years, was surprisingly left out of the 'In Memoriam' tribute at the 87th annual Academy Awards. Rivers was not mentioned in the annual segment, which honors those in the entertainment industry who passed away in the previous year.

Rivers, who also worked as a director and fashion critic, died in September after losing consciousness during an endoscopy procedure at a medical clinic in Manhattan. Earlier this month she won a posthumous Grammy award for the audio book recording of her memoir Diary of a Mad Diva.

"Am I missing something or was @Joan_Rivers really left out of the #Oscars memorials?" tweeted Kelly Osbourne, who worked with Rivers on Fashion Police.

However, Rivers wasn't the only big name omission from the In Memoriam segment, with Broadway stars Elaine Stritch, actors Richard Kiel, Gottfried John, Taylor Negron and director George Sluizer also left out. 

Meryl Streep presented the Oscar montage, in which Jennifer Hudson sang I Can't Let Go while photographs of those who had passed appeared on-screen. Robin Williams, Mike Nichols, Mickey Rooney, Lauren Bacall and Maya Angelou were among those remembered.
