Amanda Bynes is "doing well" while hospitalized in Los Angeles on a 5150 involuntary psychiatric hold, a source told Fox News.

"Amanda seems to be doing well," the insider said about the troubled starlet.

"The thing with Amanda is that it isn't as bizarre as it seems. She knows when to pull it together and act normal."

Fox News did not say what the actress' diagnosis is or how long she is expected to stay in the hospital.

Bynes, 27, allegedly caused a disturbance when she tried to break into a retirement community in her hometown of Thousand Oaks, Calif., last Sunday.

Her once-bright career has been eclipsed in recent years by her bizarre Twitter rants and frequent brushes with the law.
