On Friday night, TMZ posted what it claims is an audio recording of the former child star in which she threatened to kill her parents.
"If your father was my father … then you would understand why you'd want to slit his wrists … I haven't decided how I want to murder him … I don't believe in murder … He literally like is the worst person … Nothing would give me greater pleasure than like slitting his throat. That is what I would love to do," Bynes, 28, reportedly said in the audio file, which TMZ says was taped last week by a roommate.
"So like I'm not gonna like ever do such a thing, but like I call my mom and like I threaten to kill her, and I threaten to slit her wrist, and I threaten to like burn down her house and like I said a bunch of s––– like that," the voice continued.
And the audio file matched much of Bynes's recent Tweets complaining that her parents have cut her off financially – allegations a source close to the situation says are false.
"I'm gonna continue telling you guys I'm gonna murder my family like 'cause that's the thing that like, they're in control of my money, and that's why I don't have much money right now," Bynes says on the recording.
On Saturday evening, Bynes took to Twitter claiming her comments were made "in jest."
"I was obviously joking about hurting my family – I straight up don't believe in harming a soul," she wrote. "I said what I said in jest and if you don't understand that then know I'm in therapy to talk about my dad issues and that will solve my concerns with [people] invading my private life ... take what I say lightly because I am the nicest girl."
Bynes's lawyer David Esquibias also sent a statement to PEOPLE from the actress, reading, "I'm sorry I trusted people who clearly were not my friends and capitalized on my illness. I am doing my best to get better. I am truly sorry for the statements I made. I am sorry for any pain I caused my family and others."
It continues, "I am thankful for everyone's patience and understanding. I never expected others to take advantage and profit from my condition. I'm disappointed with those who lulled me into a false sense of security only to find out they really are only interested in selling my privacy to the media."
The alleged tape of Bynes is just the latest in a string of reports of worrisome behavior.
Despite the actress's recent antics, West Hollywood nightclub 1OAK let her and a friend in Thursday night.
"She arrived around midnight with her friend, artist JJ Brine, who had purple hair and was wearing a flower crown. She had blue hair and was wearing a T-shirt, bandage dress and platforms," a source tells PEOPLE. "She wore sunglasses in the club and had a Band-Aid on her face. They stayed for about two hours, then left in an Uber X."
And Tuesday night, TMZ reported that Bynes hit up West Hollywood tattoo parlor The Honorable Society, trying to get a tattoo of her apparent boyfriend Caleb but was turned away for having no identification.
While the shop wouldn't confirm Bynes's visit, an employee tells PEOPLE, "We need a copy of every person's ID who gets tattooed here, so if they don't have an ID or a passport or some kind of official government-issued identification, you know we can't legally tattoo them."
The actress seemed to be getting her life back together after spending time in treatment in 2013, but her behavior began to spiral out of control after her DUI arrest in September.
Bynes – who has been diagnosed bipolar – was admitted into a treatment center in California on Oct. 10, and her mother, Lynn, was awarded a temporary conservatorship over her shortly after. However, she was released from psychiatric care Oct. 30.
