While the heartthrob was supposed to be celebrating his 27th birthday on May 13, he was instead packing up his belongings after allegedly finding the messages from British director while his gilrfriend was in the shower.
"Rob was looking at her phone on the morning of his birthday as he wanted to take a picture of something when she was in the shower," a source told the newspaper.
“Suddenly this message flashes up and it’s not what he wanted to see. He got straight up and left.
"Despite Kristen’s pleas, he told her not to come to his birthday party at a friend’s that night. He’s extremely angry and upset. No matter how many times she calls or texts, friends say he’s had enough. After everything that happened and the hurt she caused, he’s furious she’d be back in touch with him, even if she is saying it’s completely innocent."

Pattinson was then spotted driving away from their home in a red truck which was full of his belongings, including suitcases.
Stewart was caught out last summer when images of her and Sanders canoodling in Los Angeles surfaced in the media.
The 23-year-old actress acknowledged their romance for the first time when she released a public apology, in which she said sorry for her actions.
She and Pattinson appeared to be back on track by the end of 2012 after promoting the final Twilight film together in November, and judging by the pictures of them at Coachella music festival last month, all seemed to be back to normal.
However, their four-year relationship may be over for good now, even if Stewart was just innocnetly texting the 'Snow White and The Huntsman' director.
Sanders own marriage has collapsed due to the scandal, and his wife Liberty Ross and since moved on after filing for divorce.
