Fergie Says Drug Addiction Gave Her Daily Hallucinations, Talks Her ‘Lowest Point’

She also opened up about caring for her son Axl during her separation from Josh Duhamel.

Fergie is coming clean about getting clean. The “Milk $” singer, 42, opened up to iNews about her struggles with addiction to crystal meth before her time with the Black Eyed Peas.

“At my lowest point, I was [suffering from] chemically induced psychosis and dementia,” she explained. “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.”

Fergie became convinced that the CIA, FBI, and SWAT teams were after her, leading to an embarrassing incident in church.

“They tried to kick me out, 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," she recalled. "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.”

She then exited the church to discover she was alone in the parking lot, calling it a “freeing moment.”

Of her past, Fergie added, “The drugs thing, it was a hell of a lot of fun… until it wasn’t. But you know what, I thank the day it happened to me. Because that’s my strength, my faith, my hope for something better.”

These days, Fergie has two major priorities in her life – promoting her new album, Double Duchess, and making her sure son Axl is being cared for amid her split from ex, Josh Duhamel.

“Both Josh and I are working full-time right now. It gets tough and we get tired, but we’re trying our hardest to make sure that kid feels nothing but love,” Fergie said of her 4-year-old son. “There’s a lot going on. That’s why we wanted to find our footing with our separation before we announced it publicly, to make sure we really got it together for our kid. It’s a constant juggling act.”

Duhamel recently opened up to ET about how Fergie is an “amazing” mom. Watch the exclusive interview below!
