The reality TV star tweeted some advice to her followers, saying: "Keep your life in a positive perspective. We are not defined by our pasts."
Ray J - who arguably sprung Kardashian to fame with their sex tape several years ago - retweeted the statement, simply adding: "LOL."
The singer has become a trending topic on Twitter since his one-word comment, which has also been retweeted over 30,000 times.
Ray J said last year that he "created" Kim Kardashian and her ongoing fame.
He also stated that their sex tape should be taken off the market, which is currently owned by Vivid Entertainment.
Kim Kardashian's current boyfriend Kanye West made his debut on Keeping Up with the Kardashians earlier this month.
