The reality star - who found fame thanks to a 2003 sex tape with ex-boyfriend Ray J - is already nine months into the first year of her legal degree and has been secretly travelling to San Francisco to complete the required weekly 18 hours of supervised study.
She will take a 'baby bar' exam this summer, and will be allowed to continue her studies for a further three years if she passes.
And while her sudden change of career direction might sound bizarre, mother-of-three Kim says she realised her calling after convincing President Donald Trump to pardon Alice Marie Johnson, 63, who had been in jail on a non-violent charge since 1996.
Kim, 38, tells the latest issue of Vogue magazine, “I had to think long and hard about this... I’ve always known my role, but I just felt like I wanted to be able to fight for people who have paid their dues to society. I just felt like the system could be so different, and I wanted to fight to fix it, and if I knew more, I could do more.”
Naturally, her husband Kanye West isn't in the least bit surprised, telling the fashion bible, "She always had it in her."
Sisters Khloe and Kourtney also didn't seem that shocked, explaining she's always been like their late father Robert Kardashian, who famously represented OJ Simpson in his murder trial.
That, and the fact Kourtney says she always "seems to have all the answers."
And CNN commentator and activist Van Jones - who worked with Kim on the Johnson case - said he's seen Kim in action and she's a force to be reckoned with.
He said: "I watched Kim Kardashian unleash the most effective, emotionally intelligent intervention that I’ve ever seen in American politics. It was remarkable. So for people who have fallen for this media caricature of the party girl from ten years ago who hangs out with Paris Hilton? This is the daughter of an accomplished attorney and the mother of three black kids who is using her full power to make a difference on a tough issue and is shockingly good at it.”
As part of her first year studies, Kim is covering criminal law, torts and contracts which includes studying affirmative duties and malfeasance, amongst other things. And some things she finds easier than others.
"To me, torts is the most confusing, contracts the most boring, and crim law I can do in my sleep. Took my first test, I got a 100. Super easy for me. The reading is what really gets me. It’s so time-consuming. The concepts I grasp in two seconds," she explains.
