Socialite Kim Kardashian has laughed off reports she's dating Chris Brown, calling the claims "so ridiculous".
Website MediaTakeOut.com (MTO) reported earlier this week (beg20Sep10) the pair had been in contact since the TV star's brother Rob handed her number over to the singer.
But Kardashian has been quick to dismiss the gossip, taking to her Twitter.com page to set the record straight.
In a series of posts, she writes, "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!
"BUT I have to say, I literally laughed out loud at these dating rumours today! Come on now MTO. I literally can't keep up anymore, not true!"
