Source: Amanda Bynes' Family Is Concerned for Her Well-Being

The Internet isn't the only one who's noticed her kooky behavior, not to mention those tweets

After giving up L.A. and acting for New York and, well, we're not sure what yet, Amanda Bynes still managed to get the world watching, just by behaving a little...strangely,

Not to mention by tweeting up a torrid storm.

But the Internet isn't the only entity paying close attention to Bynes. Her West Coast-based family is watching, too.

A source exclusively tells E! News that the What I Like About You star's weird behavior—including the at-times-raunchy tweets, the cheek piercing, the random solo outings, etc.—coupled with the myriad driving mishaps that came before, has her family concerned for her welfare.

We're told that her family wants her to return to Los Angeles so that they can keep a closer eye on her, but she refuses.

The source says that Bynes' family is hopeful that everything is going to be fine, but they're ready to step in if needed.
