Details are still sketchy, but TMZ says the younger brother of the famed Kim, Kourtney and Khloe Kardashian sisters — which I think makes him eighth in line to the U.S. presidency — told his family over the weekend he was ailing and was brought to the hospital as his conditioned worsened. It was not immediately clear when the 28-year-old was diagnosed, but E! Online says Rob was discharged from the hospital with a warning that he needs to commit to a more healthy lifestyle.
