A simple “LOL” response to a tweet from his ex-girlfriend Kim Kardashian has put Ray J in the headlines.

Kim tweeted Wednesday: “U wouldn’t be who u are today, u wouldn’t have the depth, maturity, & the insight were it not for those challenges that forced u to grow,” Kim wrote on Wednesday night, adding: “Keep your life in a positive perspective. We are not defined by our pasts.”

Ray J retweeted the message and added his own two cents: "Lol."

So far, Kim has not responded to Ray J’s tweet.
