Amanda Bynes' parents are going to court on Friday to ask for a temporary guardianship of their daughter, according to E! Online.

Bynes was detained Monday night on a 72-hour psychiatric hold after allegedly setting a fire in the driveway of a home near her parents' house in Thousand Oaks. No injuries were reported and Bynes was not arrested, but bystanders have attested to seeing the actress' pants on fire.

This is where I do not make a "liar liar" joke.

One witness told the website the 27-year-old Bynes was "frantic and discombobulated."

TMZ reported Thursday that sources close to the situation say at the facility where Bynes is staying say that she's lucid for long stretches, then goes off the handle for shorter amounts of time.

Doctors reportedly have already determined Bynes is suffering from a severe mental illness "with schizophrenic tendencies." The website reported that Bynes is aware "there's a good Amanda and a bad Amanda." Talking about the bad Amanda she almost mimics an exorcism, pulling at her body as if to remove the demon, and even biting herself.

The sources also supposedly said she's had to be physically restrained. She was initially in a room with another patient, but reportedly berated her roomate until she was moved.
