Lindsay Lohan maintains her innocence in the whole Barron Hilton beatdown drama, but now witnesses day she was a hot mess at the Art Basel Festival in Miami last week.

“Lindsay was a mess at every event at Art Basel,” a source told Radar Online. “She was so careful never to be caught with a drink in her hand and no one saw her do any drugs.” So she couldn't be that hot of a mess, right? Well, wrong.

“Lindsay would be at a party in a VIP section with Kim Kardashian and Kanye West and she would start freaking out that people were taking pictures of her and make security throw people out. But the crazy thing was, no one was taking pictures of her, if anything it was of Kanye and Kim.”

What's more, the witness says that Lohan's shortlived relationship with a young model named Morgan O'Connor drove her off the deep end. “Lindsay had a tantrum when she would see Morgan’s ex-girlfriend at events,” an insider said. “She would throw her arms in the air, stomp her feet and fling her hair around. She was acting like she was 10 years old.”

The spy added, “Morgan wants nothing to do with her at all. He is telling people that he is nervous and freaking out that his career is going to be affected by all her crazy evilness. She’s obsessed with him," the source revealed. “He is telling his friends is not her boyfriend and doesn’t want to be with her.”
