perez-hilton-amanda-bynes*The downward spiral of Amanda Bynes reached a new low on Thursday as the actress turned her ire toward gossip blogger Perez Hilton, telling him in a tweet to “kill yourself.”

@perezhilton no one wants to suck your d**k! Stop living! Kill yourself! I look sooooo much better than the girl you hired to look like an awful cheeky version of me! So I’d say F**k You but no one wants to! I just say keep living in your sh*tty existence leaching off of stars who you look, sound, and act nothing like!

Gossip Cop reports that the former “What I Like About You” star lashed out at Perez after he posted a Twitter user’s alleged eyewitness account of Bynes jumping on trampolines at Sky Zone in Buffalo, NY.

“THAT’S NOT ME! I’m so sick of fake fans such as Perez Hilton! Send the picture to me privately first to confirm that it’s me! I’ve never been to SkyZone! That looks nothing like me! I don’t own a brown wig!” the actress wrote in a tweet that has since been deleted.

Bynes’ campaign against Perez, whose real name is Mario Lavandeira, has been going on for months. The actress has repeatedly called him ugly and has threatened to sue him each time he has written an article about her.

amanda-bynes-and-perezPerez claims that he and Bynes were actually friends at one point, telling omg! Insider that the girl he knew was “normal, polite and sweet.”

“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,” he told the website of Bynes’ current state. “Amanda hasn’t been working for the last several years so [she has] no reason or excuse to be sober. So, to me, she has just been on a really long high, allegedly, for a very long time with no comedown and she’s really lost touch with reality.”

The 35-year-old gossip blogger said he’s tried to reach out to Bynes, but has only received angry messages from her in which she again calls him ugly.

The former Nickelodeon star has been tweeting her apparent breakdown on an hourly basis for months, but her outbursts have become increasingly personal and cruel since she was arrested and charged with reckless endangerment last week, after she allegedly threw a bong out the window of her high-rise apartment in New York City.

On Tuesday, Bynes lashed out at Courtney Love calling her the “ugliest woman” she’s ever seen, after the rocker told her to “pull it together.” Later that day, the actress also went after Sport Illustrated model Chrissy Teigen, telling her that she was not a pretty model compared to Bynes:

“I signed to Ford models @ age 13. I don’t look up to u beauty wise. I’m far prettier than u! I’m offended that you’re saying I have a mental illness when I show no sign of it, but thankfully not one man that wants me wants you and you are an old ugly model compared to me! You look 45!” she tweeted at Teigen. “You’re not pretty so I’m not intimidated by you! I think you’re jealous that you’re just an ugly model whos career is uninspiring! I don’t respect you! You’re no beauty queen! I’m a beauty queen!”

Though Bynes’ behavior has been increasingly worrisome and there has been speculation that she is suffering from a mental illness of some kind, it should be noted that when she was taken for a psychiatric evaluation after her arrest, authorities decided she didn’t meet the criteria to be held on a 5150 to undergo a 72 hour psychiatric hold.
