Don't believe everything you read.
Following a new report in British newspaper The People
(which is owned by the Mirror
and not related to PEOPLE magazine) that director Rupert Sanders
's affair with Kristen Stewart
was more than a one-time fling, a source very close to his wife Liberty Ross
and her family tells PEOPLE all quotes from that story are false.
"Contrary to inaccurate reports, neither Liberty Ross nor any member of her family has spoken to the media," the source tells PEOPLE. "Quotes that are being attributed to the Ross family have been completely fabricated."
report quotes a man purporting to be Liberty's brother, Leopold Ross, who says, "[Rupert and Kristen's affair took place] from the last half of filming and all through post-production, clear into last week."
Editors at The People
stand by their story. Sources have maintained to PEOPLE that the fling between the actress and director was not drawn out.
Regardless, Stewart's love, Robert Pattinson
, "just isn't going to be able to get past the cheating – one time or not," a source close to the couple tells PEOPLE. "It's something she always knew he could never tolerate."
Since news of their infidelity broke, Stewart, 22, and Sanders, 41, both issued public apologies
, and sources reported
the duo had only been intimate once. Meanwhile in Los Angeles, Pattinson, 26, and Stewart are not speaking to each other
and have both left the home they once shared, PEOPLE has confirmed.
