And the erratic behavior continues.

Amanda Bynes was spotted out and about in NYC — as per usual — on April 16. But it wasn’t her new blond extensions, sunglasses or cheek piercings that caught our attention.

The Easy A actress was clutching a Starbucks cup that read “Nadia.” The coffee company is known for writing the name of each customer on his or her order. Clearly, Amanda’s name is not “Nadia,” leaving the world to question — is this her alter ego?

From her Twitter rants — where she admitted to having an eating disorder and threatened to sue every publication that doesn’t use her personal photos — to her odd pursuit of rapper Drake, those closest to the star are fearing for her life.

In the new issue of Life & Style, on newsstands now, ex-pal Perez Hilton shares how she’s shut the world out.

“Other former friends of hers and I have tried to help for a long time,” he tells the mag. “Unfortunately, she’s not been open to that.”
