The former NBA star opted to seek treatment at a facility near San Diego, California, a year after he was hospitalised after a drink and drug binge at a Nevada brothel.

A source told Us Weekly magazine: "He went to continue making sure he stays sober and on the right path. It was something he chose to do. He did it for his kids and also wanted to feel 100 percent again. He did not relapse, but felt like he wanted to get away and start fresh for the New Year."

It was in October 2015 when Lamar was airlifted to Los Angeles' Cedars-Sinai hospital where he was put into an induced coma for over two weeks.

The news comes after it was recently revealed Lamar and his ex-wife Khloe Kardashian are officially divorced.

The 'Keeping Up With The Kardashians' beauty originally filed for divorce from Lamar in December 2013 but called it off after he was hospitalised. Once he returned to health, she refiled the papers and a judge approved them on Friday (09.12.16) in Los Angeles.

Documents confirmed the pair's joint company Khlomar would be dissolved and neither of the couple would receive spousal support. The divorce is set to become legal on December 17.

Meanwhile, it was previously claimed that Lamar is "completely out" of Khloe's life but she stills cares deeply for him despite now being in a relationship with basketball player Tristan Thompson.

A source said: "Lamar is out of her life completely. No animosity there - she still cares about him, she still wants him to be safe, but it's over."

Whilst another insider said: "They're taking it slow, day by day, but are having so much fun together. It's still the honeymoon stages and they both have a huge crush on each other.

"He's the nicest, sweetest guy, He comes from a very strong family and has a tight circle of close friends. He really isn't into the 'celeb scene' and does his own thing.

"He's close friends with [his Cleveland Cavaliers teammate] LeBron [James] and a couple of his teammates. She's very happy but taking it slow and not rushing into anything."
