Rumor has it that Robert Pattinson is no longer speaking to his ex Kristen Stewart anymore, but there's else something in his life that is reportedly getting under his skin.

Kristen Stewart Finds Happiness Again?

On Thursday, Showbiz Spy reported that the issue in the Twilight star's life is not related to his ex, but has to do with British star Benedict Cumberbatch. Apparently, Pattinson is envious of the Sherlock star because he feels like Cumberbatch took him away from the spotlight.

"Rob used to revel in his status as a British sex symbol," a source allegedly said. "He used to play it cool by pretending to be blasé about the whole fame thing, but secretly he loved it."

"Rob's annoyed that Benedict is getting all the attention and has become the hottest thing in Hollywood," the source added.

The insider then mentioned that Pattinson realized that he took his moment in the spotlight for granted.

While the actor may be dealing with jealousy, his ex-girlfriend is reportedly having her own dreadful issues, involving a possible reunion with Pattinson at Cannes Film Festival.

"Awkward is an understatement," an insider allegedly told British magazine Now published on Sugarscape. "Kristen hates confrontation, so seeing Rob will be strange for both of them."

There is a possibility that the two may not end up running into each other at the event, but if they do, it could easily create some unwanted tension between them.

"They have a lot of history together," the insider said. "Feelings don't disappear over night."
