British actors Robert Pattinson and Andrew Garfield - who spend much of their time in the United States - reportedly resent being recognised for their similar qualities.
A source told website UsMagazine.com: "The truth is, Andrew can't stand Rob. Andrew hates that they're put in the same category because they're both English and around the same age."
Apparently at the wedding of their producer friend Kevin Turen last month, Robert and Andrew spent much of the night ignoring each other, according to a witness.
The observer added: "They don't enjoy hanging out. Andrew considers himself a 'serious actor' and sees Rob as the equivalent of a cheesy boy bander because of Twilight."
A third source added that the Hollywood rivalry between the vampire saga heartthrob and The Amazing Spider-Man star is even more intense because they apply for the same jobs.
The insider said: "Both like intense parts and go after the same roles. They're just naturally competitive."
Robert Pattinson recently admitted to getting into an altercation with pop star Adele in February.
He explained: "I had this argument with Adele, which is probably the most ridiculous thing I've ever said. I was saying, 'You know, you can really just like reach for it,' and she was like, 'You do realise I am like the biggest-selling female artist ever?'"
He continued: "And I just for some reason just decided to get into an argument with her. I woke up the next day really regretting the whole thing."
