Amanda Bynes - Perez Hilton Twitter Feud Continues With 'Kill Yourself' Tweet, Bynes' Parents Fear Schizophrenia

The ongoing Twitter feud between Amanda Bynes and Perez Hilton climaxed today with the 27-year-old's darkest rant yet, with the former actress telling Hilton to "kill yourself."

The tweet came reportedly due to the gossip blogger's latest post of Bynes jumping on trampolines at Sky Zone in Buffalo, New York. Bynes has insisted it is not her caught on camera.

Following the "What I Like About You" star's retaliation, the 35-year-old blogger simply responded with, "Damn girl!"

Previously, Bynes had threatened to sue Hilton, real name Mario Lavandeira, and reportedly called him "ugly."

"The Amanda Bynes of today is repeatedly calling people ugly and is just lost. Now I don't know for sure what's going on, all of us can speculate, while I think there may be mental instability, obviously to me I think there are drugs at play," said the blogger to omg! Insider.

As Bynes' Twitter breakdown continues, her parents, Rick Bynes and Lynn Organ, have expressed concern about their daughter's mental health, even fearing schizophrenia, reports The Stir.

"Amanda has heard voices for years, and was concerned she was beings pied on via smoke alarms, and clocks in her home," said a source.

"She would cover electronic items because Amanda believed that was the only way she wouldn't be spied on. It's an extremely sad situation because Amanda just refuses to get help."

Amanda's parents, who have been estranged from their daughter for some time, have allegedly tried getting an involuntary conservatorship, similar pop sensation Britney Spears with her father in 2008.

Unfortunately, lawyers have concluded that Bynes does not meet the criteria for conservatorship.

Yet.

According to Radar Online, Bynes' parents are carefully saving all of their daughter's tweets as potential for conservatorship.

And apparently Amanda Bynes keeps feeding the evidence.
