According to People, the Easy A actress's recent drink driving arrest was the latest in a string of poor decisions made by Bynes, who feels "lost" in life.
The 26-year-old was taken into custody for DUI in the early hours of Friday morning (April 6) after hitting a police car with her black BMW while leaving a Hollywood nightclub. She was later released on $5,000 bail.
While Bynes's father Rick has insisted that his daughter does not drink, a source close to the star says that her run-in with the law was not at all surprising.
"This DUI was definitely just a serious lapse in judgment," a source told the publication. "She hit a wall personally and professionally [in 2008]... I think she's been a little lost since then."
The insider added: "[She] was raised in the industry and came up in the industry, so she has kind of a twisted head space in terms of social groups."
Last month, Bynes drove away from police during a traffic stop as the officer wrote her a ticket for talking on her cellphone while driving.
