Lamar Odom’s decision to get his life together was reportedly inspired by an old friend currently in prison for attempted murder.
Back in September, Lamar traveled to Delaware to meet with childhood friend William Gregory — who’s currently serving a 26-year-sentence.
Lamar and William chatted in the visitors’ room for 45 minutes … about Lamar’s divorce from Khloe, the demise of his basketball career and the loneliness of losing his support system.
William, who’s apparently discovered religion, went in hard on Lamar about the virtue of redemption, telling him the only way to find that road was to clean himself up.
We’re told the chitchat inspired Lamar, who mulled it over and checked himself into rehab last week, around the time of his deceased son’s birthday.
We’re just happy someone was finally able to get through to him before it was too late.
