Unfortunately being at a festival where almost everybody drinks alcohol is not the place to be when you are trying to stay sober, especially in Lindsay Lohan’s case.

A week after the 27-year-old actress admitted to relapsing with a “glass of wine” on her self-titled docu-series on the OWN channel, we find out she has allegedly been drinking something even stronger –vodka – eight months after leaving rehab.

Backstage at the 2014 Coachella Music Festival on April 12, Lindsay was spotted hanging out with her 20-year-old sister Ali and a couple of friends during Kid Cudi’s performance.

“She looked completely out of it. She couldn’t stand up straight and she was frantically chain smoking cigarettes,” an eyewitness exclusively tells In Touch. “In one of her hands she had a plastic cup with a clear liquid in it.”

The festival goer then added he noticed the Canyons star drinking like everyone else.

Lindsay shared this picture on Instagram hours before going to the festival.

“The group was standing in a small cabana, booth type thing and one of the friends was making regular trips to the bar. I overheard the friend order four vodka sodas and when he carried them back to the group,” the eyewitness alleges, “he handed one to Lindsay and she started drinking it. She didn’t seem to care who saw and none of the group seemed concerned.”

This news comes right after TMZ reported she was telling her friends she will 100% not fall off the wagon—meaning she planned on not giving in to alcohol.

The same sober promise was made last year right before she famously checked into rehab, which was then her sixth time.

Before drinking at Coachella, Lindsay tweeted “everyone please be #safe at #coachella and #smile,” which later on turned into advice she needed herself.

“Of course it’s jarring when you relapse and you try to stay sober,” she says on her show. “It’s a scary thing.”
