Amanda Bynes' Twitter rants focus largely on one subject: being ugly

The troubled and talented Amanda Bynes

The former teen star has become more known for her bizarre behavior.

LOS ANGELES – A few years ago, long before she started what has now become the Amanda Show, Amanda Bynes strutted out of a West Hollywood gym and stood for a moment, transfixed at the window reflection of herself in a tiny crop top and itty bitty shorts.

“That’s what she always wears,” another gym-goer whispered to her friend as they passed by.

Today, it seems the image in the window has played a large part in Bynes’ very messy, very public fall from grace. Amanda Bynes can't stop talking about her appearance, or the appearances of others.

Her favorite word?

"Ugly."

“F**k the ugly editors of Intouch! I'm not racist! My account was hacked,” she tweeted on Monday. In another recent twitter rant she called “ugly ex” Scott “Kid Cudi” Mescudi “an ugly duckling,” adding that “his best photos aren't s*** compared to mine at my best.”

Bynes later apologized for the “hack,” insisting that Mescudi “isn’t ugly.”

But according to that very same verified Amanda Bynes Twitter account, “Courtney Love is the ugliest woman I’ve ever seen.” She called Aubrey Plaza’s Complex cover shot “awful,” and in another recent tweet observed: “I need to get another nose job after seeing my mug shot!” In yet another she wrote:  “My dad is as ugly as RuPaul! So thankful I look nothing nothing like you both! I had nose surgery after my mug shots so my nose and I are gorgeous!”

Wait, we're not done.

Bynes tweeted Jenny McCarthy with the insult “You’re ugly!” after she posted a tweet about police coming to her NYC apartment, continuing “Aren’t u 50 years old? I’m 27, u look 80 compared to me!”

She tweeted at Rihanna, “Chris Brown beat you because you’re not pretty enough” and “unlike ur fugly self I don’t do drugs! U need the intervention dog! I met ur ugly face in person! U aren’t pretty u know it!” Bynes coined blogger Perez Hilton as “an ugly gay bully” while Us Weekly is an “ugly magazine.” And to Sports Illustrated swimsuit model Chrissy Teigen, Bynes wrote: “Ur not pretty model compared to me. I signed to Ford models @ age 13… I’m far prettier than u… You are an old ugly model compared to me! You look 45!”

So what could be going on here?

“Amanda does have huge anger issues and is paranoid about a lot of things. She just doesn’t like herself,” a source connected to Bynes told FOX411’s Pop Tarts column. “It’s not that she is obsessed with her body and appearance, but she just doesn’t seem to have any self-value right now. Calling others ‘ugly’ is her go-to for cutting others down.”

Addiction specialist Dr. Damon Raskin said Bynes is “clearly showing signs of body dysmorphic disorder, and she urgently needs psychiatric evaluation.”

“Although this could be as a result of drug use, I am more inclined to see this as a psychiatric disorder,” explained Raskin, who does not treat Bynes. “The pressure of being in the spotlight growing up could have sparked this incessant body image obsession, but more likely reflects an undiagnosed condition such as bipolar disorder.”

But as New York Magazine pointed out in an article this week, as someone who has grown up in front of the camera, Bynes has likely “weathered a great deal of beauty pressure” going through puberty in the public eye while walking red carpets and headlining feature films. At the age of 20, she told reporters that she wasn’t “in this business to show everyone how beautiful” she was or was not, didn’t seem to be bothered if she gained a little weight and condemned plastic surgery. It wasn’t until she was 23 that she took the first “sexy” step and posed for Maxim in her underwear.

“When a young child becomes a celebrity there is no training manual for how to cope and deal with stardom,” noted former model turned media educator for young girls, Nicole Clark. “The ego is a delicate thing that can easily turn harmful when left to the whims of the media and it’s obsession with someone.”

And the ever-mounting attention now devoted to Bynes could be making matters worse. Data provided to us by Yahoo! shows that in the past 30 days, searches for Amanda Bynes have spiked 92 percent, while other associated search times – including mug shot, before and after – have leapt upwards of 17,000 percent. Several image-related terms including “amanda bynes nose jobs” and “amanda bynes pictures” are also on the rise, and over 67 percent of the searches connected to the actress are coming from guys.

So in what could be perceived as either genius or exploitation, Bynes this week was propositioned by Playboy Radio – which, in a tweet, offered her the opportunity to co-host an afternoon show. A rep for the male-focused station told us they have not yet received an official response. However, she did re-tweet Playboy’s advance to her 1.8 million followers, and has so far refrained from calling them “ugly.”

A rep for Bynes did not respond to a request for comment.
