Reality TV star Kim Kardashian described her marriage to former husband Kris Humphries as a `life lesson`.

`It's just one of those life lessons that you have to learn, and it's OK,` she told Paper magazine in an interview.

Kardashian married Humphries in August 2011, but the union only lasted seventy-two days before they called it quits.

The reality star filed for divorce in October 2011, citing irreconcilable differences, however, the divorce was not finalised until April 2013.

The 34-year-old is now married to singer Kanye West and says they are `obsessed with each other`.
