The star continues to recover after being hospitalized in October
In pictures published by X17, the former NBA pro was spotted sipping on cognac at the Beverly Center mall in Los Angeles.
“He was very nice to everyone taking photos with him,” an onlooker tells PEOPLE.
Odom, 36, was alone and ordered two drinks during his time at the bar, the onlooker says.
On Sunday night, Odom’s estranged wife, 31, tweeted, “People disappoint.”
Odom spent months under medical care after being found unconscious in a Nevada Brothel in October. Odom was also spotted out drinking in March, and a medical source told PEOPLE at the time the drinking gave cause for concern.
“Lamar needs to focus on staying healthy. He should not be consuming any alcohol,” a source at Cedars-Sinai Medical Center in Los Angeles said. “In Lamar’s case, as someone who only a few months ago had several life threatening health issues, including kidney failure, he needs to live clean. The trauma to his body after the drug overdose was devastating. Alcohol can cause more damage.”
In April, Odom addressed reports that he was falling into bad habits after he was seen drinking.
“I mean, it gets tough, especially if so much gets speculated,” he told Entertainment Tonight. “Only a few people know the truth, and I just keep that close to my heart.”
