Kim Kardashian is not in a relationship with Chris Brown. The reality TV star — who recently broke up with Dallas Cowboys wide receiver Miles Austin — has denied that she’s dating the R&B singer on her Twitter account. Kardashian writes, quote, “I literally laughed out loud at these dating rumors,” adding, quote, “I literally can’t keep up anymore, not true!” The online gossip site MediaTakeOut.com was the first outlet to report that Kardashian and Brown were in a relationship. A source close to Kardashian has since told E! News that report isn’t true.
