New York: Rob Kardashian is said to be secretly dating singer Rita Ora.
The new couple were apparently set up by Rob's friend, rapper Lil' Romeo, a few months ago, but the only public evidence of their connection is a few exchanges on Twitter.
Sources claim that the relationship is so fresh that Rob's sisters 'Dancing With The Stars', Kim and Khloe may not even know of Ora, who splits her time between London and the US.
"Rob lives a life separate to the girls and is definitely a ladies' man," the New York Post quoted a source as telling.
"But he wouldn't have more then one [woman] at a time. He's a good boy," the source added.
The recent finalist of 'Dancing With The Stars' was planning to make his first public appearance with the pretty blond as a couple on Wednesday night at the Dream Downtown, where Rob was to DJ an event for Macy's new active-wear line, Ideology.
Professional dancer Cheryl Burke, Rob's partner on 'DWTS', is Ideology's spokeswoman.
