Back in November, fans rejoiced at news of an Amanda Bynes comeback.
Bynes was one of TV's most popular entertainers at the height of her fame, and her foray into film acting was highlighted by roles in such films as Hairspray, Easy A, and She's the Man.
Late last year, Bynes opened up about her drug use in a revealing interview with Paper magazine.
The actress joked about some of her behavior during the depths of her addiction, but she also spoke of her recovery in a way that indicated she takes her sobriety quite seriously.
In an effort to explain her erratic behavior and provide a cautionary tale to fans, Bynes spoke candidly about the lowest points of her addiction, including when she was too strung out to complete her work on the 2011 film Hall Pass.
"I remember being in the trailer and I used to chew the Adderall tablets because I thought they made me [higher that way]," she told the magazine.
"I remember chewing on a bunch of them and literally being scatterbrained and not being able to focus on my lines. Or memorize them, for that matter."
At one point, Bynes was placed under 5150 psychiatric hold, and it seemed unlikely that she would ever work again, or even be able to care for herself.
For the past few months, however, her life has appeared to be on the upswing, and family and friends confirmed that there's reason to be optimistic.
“Everything is wonderful,” Amanda's father said at the time.
Sadly, it now looks as though Bynes has experienced a roadblock on her path to recovery.
According to a new report from Radar Online, Bynes has checked back into rehab, apparently after suffering some sort of relapse.
Details are scarce, but the site claims that Amanda's friends and family are devastated by the setback.
Fans of the actress are maintaining their optimism, however.
After all, it's possible that Amanda is being proactive in her decision to seek further treatment.
It's not uncommon for recovering addicts to check into in-patient facilities as a sort of "maintenance" regimen.
Whatever the case, Amanda is still surrounded by a support network of devoted loved ones, and she remains under a conservatorship controlled by her mother.
We'll have further updates on this developing story as more information becomes available.
