The Wanted's Jay McGuiness showed support for Lindsay Lohan the day after she was arrested for allegedly assaulting a woman, supposedly because of a squabble over his bandmate Max George.

The band performed at New York's Madison Square Garden Thursday night, when McGuiness wore a white T-shirt bearing the image of a pouty-lipped woman and the words “Free Lindsay” scribbled in pink marker, according to the Daily Mail, which has photographs of the boy-band member's new look.

The T-shirt was making reference to an incident that took place at the Avenue nightclub in Manhattan in the wee hours of the day of the band's performance. By some accounts, the incident involved Lohan and another woman arguing over George, which led to Lohan punching a woman in the face and subsequently getting arrested.

Media reports indicated that Lohan and her younger sister, Ali Lohan, attended Justin Bieber’s concert at Madison Square Garden Wednesday night, hours before the incident Thursday morning. The Biebs and The Wanted are touring together.

Lohan -- like George, McGuiness, and another member of The Wanted, Tom Parker -- wound up at Avenue after the show.

Tiffany Mitchell, 28, was sitting in a booth near Lohan at the club, and the actress had a squabble with another woman -- apparently over George -- before she punched Mitchell in the face, according to the New York Daily News.

Lohan was arrested as she attempted to leave the club. She was taken to the New York Police Department 10th Precinct stationhouse for questioning, as was Mitchell. Both were later released.

Despite the singer already being out of custody, McGuiness decided to take a moment to address the incident in a humorous fashion.

Many found the shirt amusing, including bandmate Parker, who tweeted: “You make my life sometimes lol @JayTheWanted.”

Mitchell’s husband, Wayne Stevens, told the Daily Mail that there was an altercation going on in the club and his wife got caught in the middle of it.

“I could see there was something else going on, but we had nothing to do with it. We were just caught up in something that was nothing to do with us,” he said.

Stevens said bouncers refused to help and told him they would not throw the woman who attacked his wife out of the club because she was Lindsay Lohan. It was Stevens who called the police.
