Lamar Odom reportedly entered rehab earlier this month and his son's death years ago may have led him to do so.

According to a new report, the former NBA player checked himself into rehab in order to avoid a potential drug bender due to the boy's upcoming birthday.

"Lamar's son, Jayden, was born Dec 15, 2005, but died the following June from SIDS. We're told his son's death was the primary reason he started doing hardcore drugs ... and he was keenly aware the birthday might push him over the edge again," TMZ explained to readers on Wednesday.

Although Odom has not publicly confirmed his decision to seek treatment, the outlet claimed he had gone into a San Diego area facility sometime late last week.

In addition to his deceased son's upcoming birthday, TMZ was told that Odom was also having a hard time with the news of the finalization of his divorce from Khloe Kardashian. As the outlet revealed, Kardashian and Odom were officially divorced as of Saturday -- and he didn't want the event to lead him to use.

"Lamar is shooting for a 60 day rehab stint," TMZ revealed.

In other news, Odom is reportedly filming for a new reality show documenting his efforts to get sober.

“He went to continue making sure he stays sober and on the right path,” a source told Us Weekly. “It was something he chose to do.”
