Bynes gets all fired up: She’s in hosp for psych evaluation after ‘arson’

What a meltdown!

Amanda Bynes allegedly set fire to a California neighbor’s driveway — along with her own clothing — prompting a forced psychiatric evaluation, authorities said.

The troubled actress, 27, allegedly lit the blaze in front of a small house in Thousand Oaks, Calif., at around 8:40 p.m. on Monday, sources told The Post.

A driver first spotted the actress on the ground — with her pants on fire.

“It’s dark, it’s 8:45 and I just see her laying down, stomach up and her pant legs on fire, a trail of, you know, fire and gas, and I pull over,” said witness Andrew Liverpool. In this case, no charges were filed.

Firefighters rushed to the scene and discovered a five-foot burn mark.

“There were two burn marks, a plastic nozzle from a gas can — and a Super Soaker squirt gun,” Ventura County Captain Scott Dettorre told The Post.

Cops soon determined Bynes was responsible for the blaze — noting she was in need of “a mental health hold,” which allows forced hospitalization if the person is a safety risk.

The former Nickelodeon actress has had several run-ins with the law in the past year — including one in which she allegedly tossed a bong out of a 36th floor window in Manhattan.
