During a family spat, reluctant reality-TV star Rob Kardashian posted his sister Kylie’s actual cellphone number on Twitter on Monday night. He appeared to be upset that Kylie didn’t invite his fiancée, Blac Chyna, to a baby shower. The 29-year-old wrote, “Didn’t invite the Mother of my child to a baby shower you were trying to throw me !!? You all must have lost your damn mind.” Then Rob tweeted Kylie’s number twice, adding, “Kylie’s #….I ain’t hacked either this is rob dog lol.” The number has since been disconnected.
