The Kardashian brother had his fair share of celebrity beaver as of late, but baby brother made himself look like a sucker when tweeting scathing remarks to ex-lover Rita Ora. Though never mentioning her by name, Rob made it clear who his target was: “She cheated on me with nearly 20 dudes while we were together, I wonder how many she will sleep with now that we apart? (sic) But I mean 20?!!!” And as you can tell from her RT, our August/September 2012 cover girl got the last laugh.
