ROBERT Pattinson has taken back Kristen Stewart. The ‘Twilight Saga’ actor - who was left devastated after discovering his girlfriend of four years had cheated on him with her ‘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 on Sunday newspaper: ‘’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.’’ After the revelations Kristen, 22, had cheated on the 26-year-old hunk with married father-of-two Rupert, Robert moved out of their Los Angeles home. However, he has now accepted Kristen’s apology for her ‘’stupid mistake’’ and the pair wants to move on with their relationship.    –ES
