American reality TV star Kim Kardashian has been busy studying contracts for her bar exam lately.

The 38-year-old on Monday took to Instagram Stories and posted a video that shows her reading through her Contracts textbook and notes, reports "dailymail.co.uk".

"While everyone is probably at a barbecue, I am studying contracts today," Kim said in the video, underlining the fact that she was studying on Labour Day.

In an interview to "Vogue" in April, Kim had announced that she wanted to become a lawyer, and had begun a four-year apprenticeship with a law firm in San Francisco.

Kim developed an interest in the subject thanks to her late father, Robert Kardashian.

Robert Kardashian was a businessman and attorney, who shot to fame as a member of the legal team that defended OJ Simpson during his infamous 1994 murder trial.
