Comedy icon Joan Rivers was put on life support, her friends and family remain by her bedside while Hollywood reacts to the unfortunate news.

Rivers was having a run of the mill throat exam last week when all of a sudden she stopped breathing. She was then rushed to the hospital. It is unclear how long the fashion critic was without oxygen. Her condition jumped all over the place, but now reports are saying she is on life support.

A source said that her daughter, Melissa Rivers, is in denial about the whole situation, “She still thinks everything is going to be OK. She is refusing to admit that a world might exist without her mother in it.” That same source added, “Others that are close to Joan are starting to realize that the outcome they want is very unlikely.”

Other sources told The News that Rivers would not want to continue one with life if she wasn’t 100% and could live “a full and active life….(She) would never want to be a burden on anyone.” So far no decisions have been made on what do to do as far as continuing on with the life support or not.

The comedy world just lost Robin Williams so it comes as a huge shock that another legend would be in such bad shape so soon after. Hollywood is stunned and many famous faces took to Twitter to show their love and support for her from Larry King to Andy Cohen to Lena Dunham creator of ‘Girls’ who was famously attacked by Joan in one of her recent books who tweeted.

“We can’t lose Joan. All love and healing wishes to Her Majesty Joan Rivers- being ripped a new one by you is an honor to be treasured.”

The most heartfelt tweets came from River’s Fashion Police cohosts who knew her more than most.

Kelly Osbourne tweeted, “4 the first time in years I got down on my knees & prayed tonight! I encourage U 2 do the same 4 @Joan_Rivers my grandma! #inconsolable.”

Giuliana Rancic also looked to a higher power, “Praying for @Joan_Rivers and @MelRivers. Even though Joan’s the strongest woman I know, every single prayer counts. I love you, Joan.”
