K-Stew and R-Patz 'stronger than ever'

Kristen Stewart says her relationship with Robert Pattinson is stronger than ever - despite her cheating on him.

The 'Twilight Saga' actress shocked the world when it was revealed she had had an affair with her 'Snow White and the Huntsman' director Rupert Sanders, but she insists she has learned a lot from her "mistake" now she and Robert are back together.
