Amanda Bynes celebrated her 27th birthday yesterday, and while we don't have any sexy new Twitpics to share (the ones above were taken last week), In Touch Weekly reports that Amanda has been doing strange things in public again, and this time a member of her family has spoken up about her bizarre behavior.

During Amanda's recent month-long stay at New York City's W Times Square hotel, she reportedly came down to the lobby wearing a different wig each day, and an employee “found her curled up in the corner of the gym smoking with no pants on!”

While Amanda has insisted to the mag that she’s “not mentally ill,” she did tweet the other day that she had an imposter walking around NYC, writing, "My hair is blonde, I've never been a redhead!" Amanda since deleted the tweets, and several magazines have pointed out the the alleged doppelganger was wearing a few pieces of jewelry Amanda is regularly seen wearing.

And speaking of hair coloring, when the actress recently had an appointment at the John Barrett Salon in N.Y.C., she stunned clients when she took matters into her own hands. “Amanda said she wanted to go blond,” a salon source tells In Touch. “When the colorist finished, she didn’t think her hair was blond enough, so she started rubbing bleach through her hair with her hands. Everyone was horrified.”

Finally, when In Touch contacted her parents’ home on March 28, a woman who identified herself as a relative called Amanda’s situation tragic," adding, "She’s completely resisting any help that her family wants to give her."
