Rupert Sanders and Kristen Stewart were caught in an embrace last summer. Are they still in touch with each other?

Robert Pattinson may have decided to call it quits with Kristen Stewart after discovering recent text messages on her phone from “Snow White and the Huntsman” Director Rupert Sanders, according to a new tabloid report. Believe it?

Normally, tabloid reports based on anonymous sources are about as reliable as weather reports. Actually, worse.

But this one may have some credence, because it’s happened before.

Then-wife Elin Nordegren discovered Tiger Woods’ affair with Rachel Uchitel after finding text messages from the New York party girl on Tiger’s phone.

Before the breakup, Rob and Kristen seemed to be trying hard to rebuild their relationship. They were spotted together, looking seemingly happy at the Coachella Music Festival and later they traveled together to New York City for the Metropolitan Museum of Art’s Fashion Gala.

There were unconfirmed reports of some tensions in the relationship. But it really seemed like something pushed Rob over the edge. He gathered up his belongings and stormed off in the middle of the day.

He apparently was so anxious to make an exit he dropped his usual concern about privacy. He apparently didn’t care that paparazzi were sure to photograph him leaving Stewart’s Los Feliz house.

A text message suggesting Stewart was still in contact with Sanders after their explosive affair last summer would be enough to send anyone over the edge. In Rob’s case, he reportedly discovered the message on the morning of his 27th birthday.

As the story goes, Kristen was in the show and Rob picked up her camera to take a photo. That’s when he spotted the message from Sanders.

“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. Suddenly this message flashes up and it’s not what he wanted to see. He got straight up and left,” a source said, according to London’s Sun tabloid.

“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,” the source continued.

All things considered, the scenario makes sense. But there is no official confirmation and no way to determine whether the events actually took place.

Also, Rob’s birthday was on May 13. Why did he wait until May 19 to gather up his stuff, if he was that upset? Was it something he just put off until the weekend? That’s a big hole in the scenario, although they definitely spent his birthday apart.

“It does look like this time it’s over for good. He simply can’t trust her,” the source said. Only time will tell. Let us know your thoughts and follow TheImproper on Twitter for the latest updates on Rob and Kristen.
