Robert Pattinson and Andrew Garfield hate being compared to one another.

The British actors - who spend much of their time in the United States - reportedly resent being recognized for their similar qualities. "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," a source said.

Apparently at the wedding of their producer friend Kevin Turen last month, 26-year-old Robert and 28-year-old Andrew spent much of the night ignoring each other, according to a witness. "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," an observer noted.

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: "Both like intense parts and go after the same roles. They're just naturally competitive."
