Dina Lohan sat down with '20/20' reporter Chris Cuomo for an in-depth interview about her daughter Lindsay Lohan's struggles with addiction and the felony theft charges the actress is facing in California. Dina reveals to Cuomo that she has been aware of her daughter's troubles for some time. "I knew early on, I just didn't tell anyone about it," Dina says. "It was a personal situation."

"I saw it visually, what was happening. You know, I'm around my children. I was around Lindsay a lot, and I saw what was happening," she tells Cuomo, noting that Lindsay's troubles began almost immediately after the then-18-year-old movie star's move from her native Long Island, New York, to Los Angeles in 2004.

"She's a young girl struggling. You know, she's not perfect. She's learning as she goes, but she's learning under a microscope, so I can't even imagine how that is," Dina says. "I believe [that Lindsay doesn't drink anymore], and I think it's gonna be a lifelong struggle with addiction. But I think she's gonna be OK."
