Lindsay Lohan relapses at Coachella despite vowing to stay sober

Oh no, it’s a case of history repeating itself as Lindsay Lohan’s been spotted drinking vodka at Coachella despite promises she’d stay sober.

The fallen actress was spotted backstage at the festival with sister Ali, with an onlooker saying she was handed a vodka soda by a friend.

"She looked completely out of it," the source told In Touch. "She couldn't stand up straight and she was frantically chain smoking cigarettes. In one of her hands she had a plastic cup with a clear liquid in it."

All pretty worrying considering she’s only been out of rehab for seven months.

It comes just a few weeks after Lindsay, 27, admitted she’d relapsed by drinking a glass of wine, saying visiting LA wasn’t good for her sobriety. Check out the video at the source.
