The pair split up after Kristen cheated on the British star with ‘Snow White and the Huntsman’ director Rupert Sanders, who is married to model Liberty Ross.

An insider told Us Weekly magazine: “They are living together and have reconciled.”

Kristen may have even agreed to wed Robert, who she met on the set of the ‘Twilight Sage’ movies, as it was recently revealed he would only get back with her if he committed to her properly.

A source said: “Rob told Kristen the only way he can forgive her affair is if she truly commits to him.

"Rob has been keen to marry Kristen for quite a while and he doesn't want to get back with her unless he knows she means it for life too.

"Although Kristen broke Rob's heart he has realised he can't live without her. He never stopped loving her and he believes she still loves him.

"He is desperate to make it work and wants to give her another chance but not unless she proves she really wants it too."
