Taylor Swift is a singer who successfully crossed over from country to pop, gained fame and fortune, and has dated a bunch of other people who are also recognizeable (who's this Jake Gyllenhaal you speak of?). Harry Styles is a member of the international pop sensation One Direction. Together they have a combined 30,140,270 followers on Twitter. So, when they went on a karaoke date and returned to Swift's hotel together at 4 a.m. (holding hands!), people noticed. People like Hailie Scott Mathers, the 16-year-old daughter of Eminem. Apparently Hailie Mathers has a big ol' crush on Mr. Styles and is rather irritated that Swift is swoopin' in on her man. When she heard the news she tweeted, "if is really dating the love of my life i will not be happy.! [sic]" She followed that one up with this gem: Dear , please stop whoring around with every guy you see. We all know you're only doing it so you can make another album." Then she ran off and wrote about T-Swift in the Burn Book. Harsh. The proper response from Swift's camp would be to DM Mathers to let her know what's up. [h/t Gawker]
