A U.K. publication claims to have spoken with Liberty Ross' brother about the alleged affair between Rupert Sanders and Kristen Stewart, but sources close to Ross deny that anyone from her family has disclosed any information to the public.

The People recently published a story saying that Leopold Ross, Liberty's 28-year-old musician brother who is living in Los Angeles, revealed details about Stewart and Sanders' relationship, claiming it lasted "from the last half of filming and all through post-production, clear into last week.”

The story was in stark contrast to People magazine's original report about the affair, in which sources claimed the "Twilight" actress and the married director only engaged in a "fleeting moment that never should have happened."

Although The People is standing by its story, a source close to Ross and her family told People magazine that all quotes in the article are false.

"Contrary to inaccurate reports, neither Liberty Ross nor any member of her family has spoken to the media," the source told People magazine. "Quotes that are being attributed to the Ross family have been completely fabricated."

People also maintains that the fling between Stewart and Sanders was short-lived and began only recently.

Us Weekly, the first to break the news about the cheating scandal, published its story last week. The magazine hit newsstands on Friday and the photos of Stewart and Sanders were published online Monday.

Stewart and Sanders both issued statements apologizing for their indiscretion, but so far, their significant others have remained silent.

Ross reportedly posted some cryptic messages on her social media networks, including the Marilyn Monroe quote: "Sometimes good things fall apart so better things can fall together" and a photo of a drunken Snow White.

Robert Pattinson moved out of the Los Angeles home he shared with Stewart. Stewart and Pattinson met while filming the first "Twilight" movie in 2008 and began dating shortly thereafter.

Although Stewart issued a very publicly apology to him, Pattinson has not yet made a statement, but sources said he is devastated.

"He's so heartbroken," a source told Us Weekly. "He's shocked she could hurt him and humiliate him this way."
