As Fashion Police star Joan Rivers fights for her life at Mount Sinai Hospital in New York City, many celebrities and fans are turning to Twitter to offer their get well wishes.

We learned of Rivers’ condition last week, when we reported the comedian had stopped breathing in the middle of a routine throat procedure and was being rushed to the hospital in critical condition. Although we have recently learned that the Fashion Police star is on life support and surrounded by her loved ones, Rivers’ condition remains critical as E! puts a halt on the production of the show.

Despite Rivers being known for bashing fashion and style choices, many celebrities are turning to Twitter to express their grief over the comedian’s condition, admitting the world would not be the same without the Joan & Melissa: Joan Knows Best? star’s hilarious comments, phrases, and personality. Here are our top 10 celebrity reaction tweets honoring Joan Rivers!
