Lamar Odom poses with a young fan at a Los Angeles gas station on Monday, Aug. 26, 2013

*Lamar Odom is back home with his wife Khloe Kardashian, but remains undecided about seeking treatment for drug addiction, reports TMZ.

Odom returned to his home in Los Angeles Monday after going AWOL for several days. Sources tell TMZ both Lamar and Khloe are inside the home, but there’s still no talk of divorce — and Khloe is determined to help Lamar get his life back on track.

One source says Lamar is “open to reason and listening to the people who love him the most” … a drastic change from a week ago, when L.O. rejected an attempted intervention.

Lamar seemed to be in good spirits Monday night — when he was spotted out on a gas run near the home and stopped to pose for the above photo with a young fan.
