Harry Styles Left Taylor Swift for High Society Model and Ex, Cara Delevigne? [PHOTOS]

Aside from all the rumors coming up about the "Haylor" split, it seems that the biggest reason of all was Harry's hung-up feelings towards Burberry model, Cara Delevigne.

When Harry Styles and Taylor Swift went their separate ways after their New Year's getaway at the Virgin Gonda islands, many speculated reasons behind the sudden break-up. Some say it is because of Taylor's lack of interest in "bedroom activities." But the real cause might be that Harry still has feelings for his ex who dumped him, model Cara Delevigne.

After the two engaged in a big fight during their vacation, Taylor and Harry ended their relationship. Some sources claim that Taylor found sms messages from other women in Harry's phone, and one might be from the high fashion model.

Delevigne dumped the One Direction singer after being tipped by her modeling agency that Styles belonged in a low market, and will hurt her image as an up-and-coming socialite-slash-model.

"Harry's not used to being dumped and he hasn't got Cara out of his system, Harry's still smitten by her upmarket background, her fun lifestyle and her socialite world. It's a different world from Harry's and he wants to know what it's like from the inside. The man usually gets the girl but this one has eluded Harry and he hasn't given up" a source revealed to Yahoo OMG! as reported by Hollywood Life.

It looks like the British singer is far from being over the model, especially that Cara is reciprocating towards Harry's attempt to get back together.

"Cara likes Harry a lot but at the moment she's put her career and ambition first, but they're still in touch and Harry wants her back," added the Yahoo source.

Harry is smitten with Cara and they're secretly very close," another source told Heat Magazine.

"Harry even thinks she could be the one. He's keeping things low-key, but his dad has given his approval and thinks Cara is great. Harry sent Cara flowers and a present before she hit the catwalk for Victoria's Secret, because it was her debut. He texted her all the way through, telling her how gorgeous and wonderful she looked," added the insider.

Could one of Taylor's Harry Styles break-up songs be entitled "He Left Me For A Model?"
