One Direction singer Harry Styles is currently dating model Nadine Leopold. For the past years however, reports have continued to circulate the singer-songwriter, claiming that he is a bisexual. How is this affecting his current relationship?

Harry Styles, 21, claims to be in a happy relationship with Victoria's Secret model Nadine Leopold. The popstar is reportedly "totally besotted" with the young model. It can be recalled that Syles had also dated international superstar Taylor Swift, Cara Delevingne and just recently, Kendall Jenner.

A source revealed that "Harry has been getting more serious with Nadine," and that the singer and the Austrian beauty had been "spending lots of time together." Styles had even planned a bag of surprises and activities for the model's 21^st birthday.

Additionally, it was reported that Harry Styles' past relationship with singer-songwriter Taylor Swift, 25, has been contributing some strain on the heartthrob's new relationship. An insider stated that "Nadine really wants Taylor to get over him. She wants Harry to herself and doesn't think it's right for Taylor to draw this out anymore. She wants Taylor to go away."

The real issue however, had been always related to Styles' alleged bisexuality. In 2013, the English pop singer had been accused of dating his bandmate Louis Tomlinson. Styles reacted jokingly to this report and said, "We're not dating, no. We're just friends."

Regarding all the rumors surrounding his sexuality, the "Story of My Life" singer said: 'The only time it gets really annoying is that if you get into a relationship and you get into a place where you really like someone and then things are being written in the papers that affect them and how they see you. Then it can get annoying."

So, what is the real score on Harry Syles sexuality? In an interview with GQ magazine, Styles had revealed: "Bisexual? Me? I don't think so," and he added, "I'm pretty sure I'm not."

It seems then, that girls everywhere will just have to deal with Harry Styles' steady and happy relationship with Nadine.
