The duo - who play on screen lovers Edward Cullen and Bella Swan in the 'Twilight Saga' series - have rekindled their romance after Kristen had an affair with her 'Snow White and the Huntsman' director Rupert Sanders but it took a lot of effort by the actress to get a second chance.
The touching video made Robert realise he didn't want to throw their relationship away. "She sent Robert the film after bombarding him with hundreds of texts, emails and answer phone messages,” a friend of Kristen told The Sun newspaper.
"It was a last-ditch attempt at getting him back and she spent ages making the video montage using hundreds of photos and hours of home film footage of nights out and holidays."
It would seem that Google Chrome''s recent advert - which sees a man begging for his ex-girlfriend's forgiveness through a film - inspired the actress. The source added: "It was just like the Google Chrome ad as she cut-and-pasted lines from love poems to connect it all together."
