"Saved by the Bell" star Lark Voorhies is allegedly suffering from a mental illness, according to PEOPLE.

The former child star's mother told the magazine that her daughter is suffering from depression and bipolar disorder.

In an excerpt from the People cover story slated to arrive on newsstands this week, the magazine's writer who interviewed the star said Voorhies "wasn't right" for their meetings.

The writer claimed that during their scheduled interviews, Voorhies would often talk to herself or to people who weren't present. The writer added the former child star also ended her conversations mid-sentence.

Voorhies, however, has denied she is not well. She defended her ramblings, describing the interview process as a "hurricane."

Voorhies, a devout Jehovah's Witness, defended her awkward moments of silence during the interview.

"You caught me in moments of pray," she said "I have a strong spiritual sense." Possibly overwhelmed, she said their interview came at "a very powerful moment."

People magazine's interview with Voorhies' is her first since a Yahoo! video that went viral in May featured the actress who was barely recognizable.

In the video she had a fuller face, and is wearing garish makeup with poorly-matched color shades.

"There are things that have traumatized her," Voorhies' mother Tricia, 64 told People, "I care deeply about my daughter and I want her to resume her life... it's frustrating."

The 64-year-old said her efforts to get Voorhies' treatment have been futile- the actress has refused to seek treatment for her mental illness.

They can't explain it," Lark said about getting psychiatric care. "They can't treat it. They don't know about it." 

"She's trying so hard," said Tricia. "She says she's delayed, but she's going to get there."

Voorhies denied there was anything wrong with her. She described her mother as "over-loving" for fighting to help make her better.

The 38-year-old said she has been busy working on independent films, recording music and publishing her own books. 

However, her last major role was in 2001's "How High" with rappers Method Man and Redman about two marijuana-smoking college students.

Voorhies played the spoiled Valley girl Lisa Tuttle on "Saved by the Bell" from 1989-1994.

This fall, the former teen star is set to appear in VH1's new reality show "Miss You Much," a show about what 90s entertainers are up to.
