Kim Kardashian dismisses Brown dating reports

London: Reality TV star Kim Kardashian has laughed off reports she`s dating singer Chris Brown, calling the claims "so ridiculous".

A celebrity website had reported earlier this week that the pair had been in contact since the 29-year-old socialite`s brother Rob handed her number over to Brown, who had a violent break up last year with R&B star Rihanna.

But Kardashian has been quick to dismiss the gossip, taking to her Twitter page to set the record straight, reported Contactmusic.

"As much as I`d love to dispute every rumour, some are so ridiculous I just can`t give them attention! I`d be on here all day tweeting!" wrote Kardashian.

"But I have to say, I literally laughed out loud at these dating rumours today! Come on now. I literally can`t keep up anymore, not true!" she added.
