Harry Styles and Nadine Leopold Break Up Over Rumors of 'Flirting'?

Harry Styles is single again as it has been reported that Nadine Leopold broke up with the One Direction member.

According to Hollywood Life, the model split from Styles because she allegedly feared that he could be unfaithful to her, though the reports are currently unconfirmed.

"Harry is constantly being swarmed by gorgeous women," a source told the website. "Making matters worse is that Harry is a major flirt. Most of the time, it's harmless and he's just being playful, but it definitely affected Nadine."

"She was convinced he was cheating while on tour. She has no proof except circumstantial evidence like hearing girls laughing in the background when they talked on the phone or him having his phone turned off for long periods of time," the insider continued.

Now, Styles is reportedly trying hard to win his ex-girlfriend back. Another source from Hollywood Life claims that the boy band member is "kicking himself over losing Nadine."

"She was the first girl in a long time he's really liked and he's been calling and texting her non stop to get her back. He wants to fly her out to a show, but so far she isn't budging," said the insider.

Meanwhile, the website reports that one person who is happy about the couple's breakup is Styles' ex, Taylor Swift.

"Taylor is secretly happy they broke up," says an insider to the website. "She still has feelings for Harry and the fact that Nadine broke up with him kind of gives her pleasure. Now he knows how it feels. She never thought Harry and Nadine were right for each other anyway."
