The 29-year-old basketball player was married to the reality star for just 72 days in 2011 before she filed divorce and he now claims he pays no attention to what her or her family are doing, including her recent controversial full-frontal photoshoot.
He said: ''I'm not someone who's paying attention to things that don't really matter in my world.
''I mean, a lot of times I don't even know what's going on.''
The Washington Wizards star married Kim in August 2011 and their preparations and the ceremony itself aired on E! in a two-part TV special in early October, just weeks before Kim filed for divorce.
Kris filed his response to her petition, requesting an annulment or a decree of legal separation rather than divorce on the grounds of fraud, claiming their wedding had been used as a publicity stunt to promote the Kardashian family brand.
However, it wasn't until June 2013 that the former couple reached a divorce settlement and Kris now claims his career is his main priority.
He added to Washington radio station 106.7's 'The Fan': ''I've always been a basketball-first kind of guy. And had a lot of success through everything. For me, it's just basketball, and that's where my outlet is, especially now.''
Insisting he's not interested in his ex-wife's racy magazine spread, he added: ''But everything else, I don't really pay a lot of attention to.''
