Blair has been very candid about her battle with substance abuse. In June 2016, the actress made headlines after being kicked off an international flight due to a mix of “prescription medication and alcohol.”

“I made a big mistake yesterday,” Blair wrote in a statement to Vanity Fair the day following the incident. “After a lovely trip with my son and his dad, I mixed alcohol with medication, and that caused me to black out and led me to say and do things that I deeply regret.”

In May 2018, the “Cruel Intentions” star explained in a lengthy Instagram post that she was battling “alcoholism, depression, and anxiety,” but was living a “much healthier life” after facing her struggles head-on.

She also revealed in the post that she had been suffering from post-partum depression following the birth of her son, Arthur, in 2011.

“Crippling anxiety. I fell apart. The last moment being very public,” Blair said, referencing her airplane incident. “I was sorry. I was humbled. I stayed humble. I got better. The weight of grief began to lift. I still struggle. I cry quietly so as not to wake my child. I am a good mother… For better or for worse. I want to have hope again.”
