Amanda Bynes will be spending a little more time in a treatment facility than initially planned -- 14 extra days, to be exact.

The troubled actress checked into the Las Encinas Hospital in the Los Angeles area on Friday. Placing Amanda on a psychiatric hold for 72 hours, the center extended her stay for another two weeks, beginning Monday.

Amanda had been in New York last week where she nearly got busted for shoplifting and announced via social media that she was moving there. Arriving at LAX airport Friday afternoon, she was quickly checked into the treatment facility. Her parents Lynn and Rick Bynes were spotted visiting their daughter at the center shortly after her arrival, E! News said.

While it isn't exactly known what she's being treated for, Las Encinas offers "a wide range of behavioral health care treatment options ... for patients with psychiatric, chemical dependency, or co-occurring disorders," according to its website.

Just hours before being checked into the facility, Amanda took to Twitter to allege a series of shocking and unsubstantiated claims about her father, making several claims of sexual crimes against him.

"My dad was verbally and physically abuse to me as a child," she wrote. "He called me ugly as a child and then asked me if I wanted to have sex with him and i did not know how to respond and I said no and then I was forced to live with my dad which was a total nightmare."

After a firm denial of the allegations via Lynn's lawyer, Amanda deleted the tweets and also recanted the allegations via Twitter, albeit with a strange explanation.

"My dad never did any of those things," she wrote. "The microchip in my brain made me say those things but he's the one that ordered them to microchip me."
