While the entertainment world is mourning a true pioneer in female comedy, Jenni "JWoww" Farley has remained very quiet on her social networking accounts. Rivers passed away today at the age of 81, but back in July, JWoww slammed the comedienne by saying "I cannot believe she's not dead," in a podcast rant.

Many celebrities from Sharon Osbourne to Kelly Ripa, Joel McHale and so many more are offering their condolences to Rivers' family, including her daughter Melissa Rivers, but it looks as though JWoww has nothing to say. Even JWoww's co-star and friend, Nicole "Snooki" Polizzi, expressed her sadness on Twitter by writing, "RIP #JoanRivers" on Thursday afternoon.

Back in July, JWoww slammed Joan while calling her "rude."

In her pal Snooki's weekly podcast, the reality television star attacked Joan as they were discussing the comedienne's decision to walk out of an interview with CNN on July 11.

JWoww said during the podcast, "She can't take the heat. Oh, but she can dish it!"

The former Jersey Shore star also dismissed Rivers' claims that she "never feels the need to apologize" to people about her controversial jokes because in her opinion, she's telling "the truth."

"It's not truth, it's her opinion," JWoww added. "Your opinion is not fact, you (expletive) cow. I can't believe she's not dead."

She added, "She's rude, that's all she is, and she hides behind her rudeness by saying that they're jokes. They're not jokes."

Joan passed away in New York City Thursday after spending the last few days on life support, following complications she had with minor throat surgery.
