Oprah Winfrey has fuelled speculation that her relationship with Stedman Graham is over after reportedly leaving him out of her will.

MSNBC's The Scoop claim that the media mogul has drawn up papers outlining the distribution US $2 billion fortune - which overlooks her partner of 21 years.

The report goes on to claim that Winfrey plans to donate part of her fortune to numerous charities - as well as her three yet-to-be adopted daughters.

"(Adoption) is something she has always wanted to do" claims a source. "There's no talk of her adopting the children with Stedman - this is something she's going to do by herself."
