The celebrity website ‘TMZ’ reported that he was looking at Kristen’s phone when he saw the messages from the director Rupert Sanders – who Kristen had an affair with when the pair shot ‘Snow White and the Huntsman’ – leaving him heartbroken on his 27th birthday on May 13.
Rob decided to leave right away and he was recently photographed moving his possessions out of Kristen Stewart`s LA house on Monday.
