Doctors are expecting to bring Rivers out of her coma this weekend and will evaluate the damage caused when she went into cardiac and respiratory arrest, according to the Daily News.

Rivers has documented her life in the reality show “Joan and Melissa: Joan Knows Best?” and gave fans a rare look into her off-stage life through her 2010 film “A Piece of Me.”

“So, my stage persona is just, I like to represent all of the women,” Rivers said. “My real life is my real life. Hostesses invite me and think ‘Oh, Joan will be the life of the party and we will put her at that table’. If I don’t know you, I don’t talk.”

The comedian has also written 12 books. She sat down with KCAL9 in 2012 when her satirical memoir “I Hate Everyone Starting With Me” was banned at Costco.
