Not so fast!

Reports surfaced this week that Rob Kardashian had moved on from Blac Chyna and was dating reality star Mehgan James, but he says that's not true! "Wait reading online about some chick I'm dating Megan something. Not true never even met her or heard of her before," he tweeted yesterday.

James then retweeted his comment and added her own response.

"Less is more. Although I've been advised not to say anything , I will say, I'm only 'Megan something.' I don't control the media but we all know who does. Im just as confused as everyone else," she wrote. Hmm... is she implying the Kardashians are spinning stories for publicity?

This doesn't mean he's holding out for a reconciliation with his baby mama, though!

"He has been happy and understands that he and Chyna are not a match. Both of them do better without each other," a source dished to Us Weekly.

He should stay single and work on himself, rather than get involved with all these fame hungry gold diggers!
