Is This the End for the Twilight Lovebirds?

According to reports in the media Kristen Stewart has cheated on Robert Pattinson with Rupert Sanders who directed her on Snow White and the Huntsman.

Us Weekly claims there are recent pictures of the actress and director having a ‘marathon makeout session.’

Stewart and Sanders worked together on Snow White and the Huntsman.

As yet no official representatives have spoken out about the allegations on behalf of any of the parties involved.

However a source did tell People that Stewart is ‘devastated’ by what is referred to as a ‘complete lapse in judgement.’ The source also explained that she wasn’t having an affair with Sanders but just a ‘moment.’

While Stewart has been unofficially dating her Twilight co-star Pattinson for three years now, Sanders is married to model Liberty Ross with whom he has two young children.

Stewart and Pattinson met on the set of Twilight and have been dating for three years. 

Director Sanders is married to model Ross and together they have two children.

If the rumours are true it could make the promotional tour for the upcoming Twilight Saga: Breaking Dawn – Part 2 very uncomfortable.
