Kristen and Robert

Robert Pattinson - who was left devastated after discovering girlfriend Kirstin Stewart had cheated on him with 'Snow White and the Huntsman' director Rupert Sanders - has decided to give the actress another chance after realising he can't live without her.

A source told The Sun: ‘They pretty much decided they couldn't live without each other. Kristen poured her heart out to Robert and told him it was a one-off and a mistake.'’

They have begun making amends by moving back in together and will now be gearing up towards their first public appearance at the premiere of 'Breaking Dawn - Part 2'. How convenient...
