Well you might be aware of Rob Kardashian's big Twitter spaz out on Twitter yesterday, while accusing his girlfriend/British singer Rita Ora of sleeping with 20+ dudes during their one year relationship.

"Ty Ty, who is Jay-Z longtime best friend and an executive at Roc Nation, was the one who discovered Rita and begged jay to sign her to the label. 

But this was when Rihanna was going through her downward spiral rated 'R' days and Ty Ty thought having another younger female artist with singing chops on management would be great. 

So he and A&R's Rita from day one, shaping her image, her song picks etc..when he got wind she was f*cking around with rob he was LIVID..the whole point of having her on the label was to have a wholesome version of Rihanna, big endorsements without the weed pictures and over partying.

The source then added: 

Since she got with him and began to record exclusively in Los Angeles, she was out almost every night, he had to send people to the clubs to get her to the studio, he basically told her she has one shot, and if she ruins her image, that's that.

So that explains why Rita has been oddly quiet about the reports, because her career might be on the stand-still.

And since then, Rob has retracted his story about the British singer. So you can read more here.
