What a mortifying relapse.

Selma Blair was sober for three years before her recent in-flight meltdown, Life & Style reports. In fact, she only began drinking during that trip to Cancun with ex Jason Bleick and son Arthur.

In case you missed it, Blair was returning from her vacay when she drank lots of wine during the flight and was seen mixing some sort of medication with her alcohol. She then became belligerent and screamed "He burns my private parts. He won't let me eat or drink. He beats me. He's going to kill me." A pilot radioed ahead to ground crew to have EMTs on hand as soon as they landed, whereby medical personnel boarded the plane and carried Blair off on a stretcher.

Following her episode, the Cruel Intentions star released a statement.

"I made a big mistake yesterday. 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. My son was with his dad asleep with his headphones on, so there is that saving grace. I take this very seriously, and I apologize to all of the passengers and crew that I disturbed and am thankful to all of the people who helped me in the aftermath. I am a flawed human being who makes mistakes and am filled with shame over this incident. I am truly very sorry," she explained to Vanity Fair.

The troubled actress reportedly suffers from depression and made the decision to abstain from alcohol in order to be a better parent to her son. "Yes, she has problems, but that kid is her life," the source added.

We hope she gets the help she needs!
