Lamar Odom reportedly checked into rehab a few days ago but the NBA star apparently didn't stay for long.

TMZ reported that Odom has been walking the streets of Los Angeles in the wee hours of the night, stopping at sushi restaurants and convenience stores. A photo agency snapped pictures of him early on Monday as he walked around downtown L.A. after midnight. According to the photo agency, Odom went back to his downtown apartment and came back out at 3:15 in the morning and went into someone's car. He left that car a few hours later and went back home at 6 a.m.

TMZ said that Odom's dealer has ditched him because he's afraid of the backlash with all of the media attention.

"Sources connected to the dealer tell us the crack slinger had delivered the drug to Lamar all summer, but last week, Lamar was insatiable. ... His go-to dealer apparently got scared enough to cut Lamar off,"

People Magazine reported on Thursday that Odom checked into rehab. That came a week after Odom was arrested on DUI charges. Reports had said that his wife, Khloe Kardashian, tried to stage an intervention but he resisted and ended up holing himself up in a hotel with friends. TMZ said a criminal defense lawyer stayed with Odom for six weeks in June and she reportedly saw him smoking crack while he was with her.

Odom was being pursued by the Lakers and Clippers this off-season, but his problems off the court have likely turned all NBA teams away for now. It's hard to see him returning to the league anytime soon.
