Just hours after Lindsay Lohan was arrested to punching a woman in the face at a New York City night club, The Wanted band member Jay McGuiness made a public display of support for the troubled actress.

McGuiness and his band mates Tom Parker and Max George were with Lohan at the Avenue night club in New York City's Chelsea neighborhood where she was arrested around 4 a.m. and taken to NYPD's 10th Precinct.

The next day, The Wanted appeared with Justin Bieber at Madison Square Garden, and McGuiness wore white T-shirt with a hand-made message in pink marker that read, "Free Lindsay."

While Lohan partied at the night club with members of The Wanted, witnesses saw her drinking heavily, and she was reportedly using drugs, according to new reports from Perez Hilton.

"She was drinking Grey Goose and also champagne. The vodka bottle was right in front of her. Lindsay was completely out of control. She was drinking way too much booze and was doing cocaine," said a source who was at the bar that night.

TMZ reported Friday that Lohan's behavior has spiraled out of control in recent days, and the 26-year-old has been drinking as much as two liters of vodka per day.

"According to sources, Lindsay's become so stressed by her dire financial situation and the impending probation violation -- stemming from her PCH crash this summer -- that she's turned to alcohol for relief," TMZ reported. "We're told Lindsay -- who's struggled with substance abuse in the past and even has a DUI conviction under her belt -- would often begin drinking first thing in the morning, and continue drinking throughout the day."
