The couple split in June, when it was revealed that Kristen had cheated on her Twilight Saga co-star, with married director Rupert Sanders.

The pair had worked together on Snow White and the Huntsman.

But it’s claimed today that Robert has forgiven K-stew and the couple have reconciled.

However, Rob fears a backlash from fans and is worried that the relationship might affect his career so he wants to keep the reunion under wraps.

The stars have not been seen together in public since pictures of Stewart kissing Sanders were printed in a US magazine.

The actress pulled out of a planned joint appearance with Pattinson at last week’s MTV Video Music Awards – instead opting to promote On the Road in Toronto.

And she recently insisted their personal life will not affect their promotion of “Breaking Dawn Part 2” which is released in November.
