Harry Styles slams Taylor Swift in the new One Direction movie titled This Is Us. According to a Daily Mail report, Styles claims that his ex-girlfriend was a "pain in the a--". Harry said, "I think I've been unlucky in love so far, but then, I haven't really met anyone who's made the earth move for me."

In addition to speaking out against country-pop princess Taylor Swift in the movie, Styles also opened up about what kind of relationship he would like in the future.

"I'm longing to meet someone who really inspires me and makes me really want to spend time with them."

According to Internet rumors, Styles slams Taylor Swift in a rant about his famous ex girlfriends. The Daily Star quoted the One Direction singer as saying, "I haven't met a girl yet who I'd want to even think of getting serious with."

At the ripe old age of 19, Harry has been romantically linked to some of the entertainment industry's most famous beauties, including Caroline Flack, Lily Halpern and Cara Delevigne, in addition to Taylor Swift.

An anonymous source commented on Styles and Swift's breakup in January of this year, saying, "Taylor is so concerned that the public will think she's a whore because she dates around, that she doesn't put out. What she doesn't get is that the guys keep dumping her because she's being a prude."

Another source added, "Harry found Taylor a little sexually uninterested," and that Swift talked too frequently about "antiques." 'Too much antique talk' is an odd reason to break up, but perhaps the documentary about Styles' group will shed some light on the split.

One Direction's upcoming 3D film This Is Us, billed as an all-access backstage pass to the British boy band's live concert, is scheduled to open in theaters on August 30.
