Amanda Bynes is surrounded by love and support from her fans, family, and past co-stars.

The former Nickelodeon actress is preparing for her forthcoming conservatorship hearing, and her "All That" castmates are rallying behind her.

The hearing will take place on Tuesday, when the 35-year-old will attempt to be heard in court in order for her conservatorship to be terminated.

Leon Frierson allegedly insisted on being present in the court to lend moral support to the "She's All That" actress.

Christy Knowings, who also appeared on the show, is supporting Bynes even though she can't be there in court like Frierson.

TMZquoted her as saying, "If it were me, I would want people to rally behind me. Amanda is a vastly different person today than she was back then, as are we all."

While Knowings confessed to the source that she and Frierson haven't spoken to Bynes in years, they both still care for the troubled actress. They also claim to have no ulterior reasons for openly expressing their support.

"I know Amanda's a wonderful person, and I liked working with her," Knowings asserted.

The actress' lawyer, David A. Esquibias, also informed the site that she appreciated the love and support she is receiving from her former castmates.

Amanda Bynes officially petitioned to dissolve her conservatorship in February, following nine years under her mother's legal custody.

Her conservatorship was established in 2013, and she was hospitalized for an involuntary mental detention after reportedly lighting a minor fire in a neighbor's driveway.

In 2014, Bynes stated that she had been diagnosed with bipolar illness and manic depression.

While battling drug addiction, Bynes was in and out of mental health facilities for several years. Her legal team now believes that she has been trying hard to live a healthy lifestyle.

Her lawyer said last month that they all feel her health has improved and that she no longer need the court's protection.

With Bynes' hearing scheduled for tomorrow, she is preparing to make her case by having her facial tattoos erased, which she described in an Instagram picture earlier this month.

Amanda Bynes' conservatorship is different from Britney Spears' who claimed that she was abused and plans to sue her parents, Lynne and Jamie Spears.
