Just a few days earlier Affleck, 47, was busted falling outside a wild Hollywood party in the early hours of the morning.
At the Halloween bash, a UNICEF party in La Peer Hotel, an eyewitness told the rehab alum “downed clear drinks, like either vodka or tequila” while wearing a skeleton mask.
“I guess it was a disguise,” the onlooker said, adding that it didn’t look like any of his friends were attempting to stop him.
“You could tell he was so out of it,” the fellow partygoer told Radar. “He was clearly plastered.”

Affleck was on hand to help Sam for the festival holiday on Oct. 31.
“It happens, it was a slip, but I’m not going to let it derail me,” he told photographers the day after he was filmed stumbling out of the party.
In a disturbing video obtained by TMZ, Affleck — who wore a black outfit and white skeleton mask — was seen wrapping his arms around a young woman outside before losing his balance and struggling to hold himself up. As photographers asked him questions, he slowly made his way to a black SUV and slid in.

“Battling any addiction is a lifelong and difficult struggle,” Affleck wrote one day before his boozy relapse. “Because of that, one is never really in or out of treatment. It is a full-time commitment. I am fighting for myself and my family,” he wrote on Instagram.
