George Kotsiopoulos, Joan Rivers' “Fashion Police” co-host, took to Twitter to pay tribute to Rivers after the comedian passed away Thursday at Mount Sinai Hospital in New York. Rivers' death at age 81 came after complications from throat surgery last week. Her daughter, Melissa, announced Rivers’ death after she was removed from life support. The comedian leaves a legacy of more than five decades of brutal, no-holds-barred comedy that pushed the limits for women in comedy and on television.

Rivers was famous for her fashion commentary and celebrity gossip, both making fun of and reporting on fashion trends and celebrity wardrobe choices. She appeared on E! and TV Guide, as well as other channels, numerous times to report from red carpet events and award shows. She also hosted the show “Fashion Police” on E! with Giuliana Rancic, Kelly Osbourne and Kotsiopoulos.

Kotsiopoulos tweeted an emotional response to the comedian’s death, thanking Rivers for her impact on his life:

Both E! and “Fashion Police” posted on their Twitter pages as well, paying respects to the television personality:

“Fashion Police” co-stars Rancic and Osbourne have not yet taken to Twitter to comment on Rivers’ passing. Rivers had hosted the show on E! since 2010 when she returned to the network after reporting from and hosting red carpets for TV Guide. She had previously done so for E! until 2003. Rivers also starred in the reality show “Joan & Melissa: Joan Knows Best” with her daughter on WEtv.
