Olivia Newton-John’s daughter Chloe Lattanzi falls off the wagon, posts pictures to Instagram

SHE spent months in rehab, but now Olivia Newton-John’s daughter Chloe Lattanzi has blown her sobriety in a night of wild partying.

SHE spent seven months in rehab dealing with drug and alcohol addiction, but now Chloe Lattanzi has admitted to falling off the wagon.

Taking to Instagram, the 29-year-old wrote: “If you’re sober stay sober. I went out last night and p****d my sobriety away.

“Keep your sobriety. You never regret not drinking.”

Lattanzi, who’s not afraid of a selfie, accompanied her post with a string of photos in various poses, outfits and blank stares.

Later, she posted another quote: “The only person you should try to be better than, is the person you were yesterday.”

In the past, Lattanzi has said that she blames anxiety for her problems with anorexia, cocaine, alcohol, and antidepressant abuse, even admitting she’s often been high in front of her mum, Olivia Newton John.

Speaking in an interview last year, Lattanzi spoke of her addictions.

“I never developed any tools for coping with my emotions. The only way I knew how to deal with emotional stress was through self-harm. That’s why I started doing drugs and drinking,” she said.

“The first time I tried cocaine I felt such relief. It took my anxiety away.

“I got to the stage where the first thing I did each morning was to do cocaine. I was drinking and partying and going crazy.”

She recently said in an interview that she hopes to work with Lady Gaga.

“I want to improve on my craft even more and I’m writing some music for a film right now that’s being shot.”
