amanda bynesThis Amanda Bynes meltdown gets more bizarre by the day. After two hit-and-run charges while driving on a suspended liscense, the star reportedly locked herself inside a public bathroom in New York City.

Okay. Now I'm seriously worried about the poor girl. This has to be the strangest turn yet. Obsessively hanging out in your car is one thing, but an NYC public restroom. That's weird and gross!

According to witnesses, Bynes stopped into the Little Cupcake Bakeshop in Manhattan's SoHo neighborhood. Though it was 9 p.m., she was sporting sunglasses and ordered a Dreaming Princess cupcake and cappuccino with extra sugar. Doesn't sound all that crazy so far, right? Just wait.

After getting her goodies, she headed into the bathroom where she stayed for more than 30 minutes. Other customers began to worry about her, including a fireman who tried to figure out what was going on with the star. Explained one onlooker:

He knocked on the bathroom door numerous times and called for her. The workers at the bakery even turned down the music to see if they could hear any noise coming from the bathroom. He tried to get her to respond, through the door, for almost 15 minutes. Finally, he called the police and asked if he had their okay to break down the door.

She didn't utter one word. No response at all. Her silence just made everyone worry even more. Fearing she was unconscious, the firefighter was going to break down the door, but then suddenly, Amanda emerged nonchalant, as if she'd just taken a quick tinkle. A bakery employee then escorted her out the back door.

Amanda was also reportedly acting oddly during a gym class recently. She walked around trying to go to a bike nearer to the mirror and then removed her top, revealing a tiny, black strapless push-up bra instead of a sports bra. Then, 20 minutes in, she stopped pedaling to pick up her purse and reapply her makeup. Ten minutes after that, the instructor threw her out.

Poor Amanda. What in the world is going on with this girl?

Does Amanda Bynes' behavior worry you?
