Most know Fergie as the talented singer who became famous while a member of the Black Eye Peas.
She quickly went on to become a household name through her budding solo career and marriage to Josh Duhamel, an actor and former male model of the year.
And from the outside, it seemed like she was living a life that most could only dream of. Although for her, it truly was.
The singer/dancer recently opened up about her life prior to fame and fortune, a life most couldn't conjure up in their worst nightmare.
During an interview with iNews published Thursday, the Black Eye Peas star opened up about her crystal meth addiction prior to entering the musical group and how it led her to a year of psychosis.
"At my lowest point, I was [suffering from] chemically induced psychosis and dementia.
I was hallucinating on a daily basis. It took a year after getting off that drug for the chemicals in my brain to settle so that I stopped seeing things."
The 42-year-old mother, whose real name is Stacy Ann Ferguson, said of her addiction:
“The drugs thing, it was a hell of a lot of fun … until it wasn't.”
During the interview, she recalled one moment in church where she had a psychotic breakdown, thinking she was being chased by the CIA, FBI, and a SWAT team:
“They tried to kick me out [of the church], because I was moving down the aisles in this crazy way, as I thought there was an infrared camera in the church trying to check for my body.”
But it was during this moment that Fergie remembers putting her own mind to the test telling iNews:
“I bolted past the altar into the hallway and two people were chasing me. I remember thinking if I walk outside, and the SWAT team's out there, I was right all along. But if they're not out there, then it's the drugs making me see things and I'm going to end up in an institution.”
And when she ran outside, she saw firsthand how drastically the drugs had affected her, seeing no SWAT, CIA or FBI teams in the church parking lot. She called this moment “freeing.”
The singer's hallucinations were quite common for crystal meth abusers, however, Fergie, unlike many of the people who suffer from addiction, was able to find help.
She credits hypnotherapy for her recovery, and she has now been clean for 18 years.
Fergie recently made headlines because of her split from husband Josh, who she married in 2009.
The two have one son together, Axl, who they plan to co-parent.
