For no good reason at all, actor D.B. Sweeney went on a Twitter rant on Friday with the innocent victim being fellow actor Robert Pattinson. Putting his nose where it doesn't belong, Sweeney chimed in on the whole Robert Pattinson/Kristen Stewart cheating scandal and then went OFF on a the Twilight fans who weren't so happy with his tweet.

Sweeney tweeted, "Just saw Pattinson on #DailyShow trying to figure out what took k-stew so long to look around with douche astride her. #holytwit." Angry Pattinson fans instantly began firing off at Sweeney with tweets like, "I hate you. Do not mess with Rob," and "Don't talk sh** about the greatness which is Rob when your credentials can't even match his." 

The tweets didn't get the now hated actor to back down, he responded with, "Hey #twilight genuises--try decaf! A little too worked up over a skinny vampire," and "Nice language twi-hards. Or should i say tards? Love the inchoate indignation," and "Dear twihards. Its been a difficult time. First tom and katie. Now rob and kristin im in a spiral. Youre caring abuse has been a comfort."

Clearly this guy has no placing blasting Rob and justifying Kristen's "indiscretions"... SERIOUSLY... Just look at him. And seeing that Twilight has made millions and has a HUGE following, it really isn't a wise career move for D.B. Sweeney to be disses them.... Don't you think?
