Amanda Bynes' bizarre behavior has finally caught up with her.
The 27-year-old actress was hospitalized on a 5150 hold Monday after setting a small fire on the driveway of a random residence in Thousand Oaks, CA. TMZ broke the story.
The sheriff's deputies that responded to the scene questioned Amanda -- and based upon her answers -- determined she needed to be placed on a 5150 hold -- an involuntary hospitalization for mental evaluation. She can be held for up to three days.
This is the latest in a string of odd incidents involving the former child star.
Last Thursday, Amanda was reportedly kicked out of the Ritz-Carlton in New York City after allegedly smoking marijuana in her hotel room and insulting a front desk attendant.
Earlier last week, she donned a teal wig to court on charges she through a bong out of the window of her New York City apartment. She's also taken to Twitter to post odd "selfies" and attack everyone from Miley Cyrus to the Obamas.
