(Cover) - EN Showbiz - Rob Kardashian has a new girlfriend, it is being reported.

The Dancing with the Stars contestant recently began dating Dollicia Bryan. She is the ex-girlfriend of his sister Kim's former lover, Reggie Bush.

The NFL star apparently started dating Dollicia soon after the end of his three-year relationship with Kim.

Although Dollicia denied the fling, she told King magazine at the time that she was a "younger, hotter version" of Kim and sniped that the reality star was only "famous for leaking a sex tape".

But it appears Kim's 24-year-old brother does not care about the past and was seen leaving the Hollywood Roosevelt hotel on September 1 with the 27-year-old.

"Rob is disrespecting his big sister by dating the girl who disrespected her," a source told Star magazine. "It's quite the slap in the face for Kim."

Dollicia even took to her Twitter page last week to urge fans to vote for Rob after his performance on the hit dancing show. (C) Cover Media
