 Just days after chasing a homeless person in Times Square and being arrested during a Broadway performance of Cabaret, LaBeouf emerged back in Los Angeles on Monday afternoon, according to x17Online — and onlookers couldn’t help but notice the giant blue Alcoholics Anonymous book clutched in his hand. Known by AA members as The Big Book, it is the central text of the program and considered essential reading for anyone trying to get and remain sober. Not long after, according to the report, he checked into rehab, looking “nervous” and “like he didn’t want to do it, but knew he had to,” an eyewitness said. 
 
 Is he finally ready to give up drinking? This isn’t the first time that LaBeouf has dabbled in recovery.

 The actor admitted long ago to attending AA meetings as a child, accompanying his father. He managed to stay on the straight and narrow as a teen, crafting a promising film career, but after a 2007 arrest at a Walgreen’s for what he admitted was “intoxicated” behavior, and a 2008 drunk driving arrest, it was clear he was developing issues of his own. 
 
 In 2008, the National Enquirer reported that he had recently taken a chip celebrating 60 days of his own sobriety at an L.A. AA meeting.

 By 2011, he was ready to go public with his problems, telling Parade that he was an “alcoholic” after a messy bar brawl. 
 
 He was also spotted frequenting AA meetings in both New York and L.A., insiders tell Radar. 
 
 But by the next year, there were concerning signs he was off the wagon when he bragged about drinking moonshine and dropping LSD for movie roles.

– Did Shia LaBeouf's crazy night on Broadway last week finally convince him it's time to get help? Maybe: After he was kicked out of a theater and arrested Thursday night, LaBeouf checked into rehab in LA yesterday, x17 reports. LaBeouf was also seen toting Alcoholics Anonymous literature, Radar notes, adding that this isn't LaBeouf's first experience with AA: He reportedly celebrated 60 days of sobriety at an AA meeting in 2008, and in 2011 he admitted he was an alcoholic publicly and was seen attending meetings. As TMZ points out in numerous articles, the Broadway incident was just the latest bit of misbehavior from LaBeouf: Last month he was banned from an LA restaurant for peeing on its outside wall; earlier this month he was recorded trying to fight outside a New York strip club; and hours before his arrest Thursday, he chased a homeless man after a weird argument over a hat the guy was wearing. And then, of course, there was his 2011 bar brawl, his 2014 bar brawl, that whole debacle with Alec Baldwin, the paper bag incident, and his bizarre plagiarized apology tour.
