Demi Lovato's had a charmed life, going from a child television star on Barney & Friends to a multi-platinum pop sensation. (Unfortunately, she's never covered the Barney "I Love You" song.) However, she's also struggled with her inner demons, battling an eating disorder, bipolar disorder and substance abuse.

Thanks to rehab, Demi has been sober for six years. It hasn't been easy for her to avoid temptation, but strangely enough, being a famous celebrity has helped. In a new interview with Billboard, she says that brutal honesty "holds me accountable. When I started talking about my sobriety -- I can never be seen at a club getting wasted. If I relapse, it shows my fans it’s OK to relapse."

If you have an addictive personality, resisting alcohol can be challenging. If something good happens, you want to celebrate with a drink. If something bad happens, you want to drown your sorrows with a drink. If you're bored, nervous, scared, stressed out - virtually every emotion turns into an excuse to hit the bottle. And that includes being annoyed by a 'complete bitch.'

In the interview, Demi tells a story about attending the 2016 Met Gala, a star-studded fundraiser for the Metropolitan Museum of Art’s Costume Institute. Vogue's Anna Wintour oversees the event, which is colloquially referred to as "fashion’s biggest night out."

“I had a terrible experience. This one celebrity was a complete bitch and was miserable to be around. It was very cliquey. I remember being so uncomfortable that I wanted to drink."

The 25-year-old pop star doesn't reveal who that stuck-up celebrity was, but she does reveal that she found the strength to avoid grabbing a drink at the bar to take the edge off. Instead, she did the right thing, texting her manager and ditching the the Met Gala for a 10 pm Alcoholics Anonymous meeting. But coming from the glitzy fashion party, she was wearing a custom Moschino gown - not exactly the attire most people wear to AA.

 "I changed my clothes, but I still had my diamonds on — millions of dollars of diamonds on in an AA meeting. And I related more to the homeless people in that meeting who struggled with the same struggles that I deal with than the people at the Met Gala."

Congratulations to Demi for not relapsing, even in the presence of a 'mean girl.' I know you're disappointed she didn't identify who the 'complete bitch' celebrity was, but she's not really the type to name names. Recently she tweeted that a performance of "Sorry Not Sorry" was aimed at a bully sitting the audience of her concert. Celebrity blogger Perez Hilton fired back at her on Twitter, believing she was talking about him, and she probably was, but the singer did not confirm. So, I guess you'll have to comb through photos of the 2016 Met Gala and speculate. Get on it, Internet.
