Taylor Swift is really good at creating songs about her former lovers and her secret was finally revealed.

Her latest single titled "Style" was rumored to be about her ex-boyfriend Harry Styles" and it seems that the rumors are true. Why? In her music video for that song, she showed a paper airplane necklace, which according to reports belong to the One Direction member.

US Weekly reported that the 25-year old singer was seen wearing the same kind of necklace which she often borrowed from the One Direction member when they were still together. Could that mean that she is still not over the 21-year old British singer?

Latest reports revealed that apart from Harry Style's airplane-designed necklace, Taylor Swift has kept other belongings of her ex-boyfriends.

"Taylor collects and keeps mementos from all of her relationships," a source told Hollywood Life.

According to the celebrity site, she has Jake Gyllenhaal's bracelet and scarf, Taylor Lautner's comfy shirt, John Mayer's guitar picks, and Conor Kennedy's tie. Could she still be obsessing over her former lovers?

Usually, women who want to get over their ex-boyfriends get rid of the items that remind them of their past relationships. That's why it is surprising that Taylor Swift has kept them all.

"She uses the mementos to help her remember her relationships and write emotional lyrics," their source revealed. So this must be her secret to writing a successful breakup song. Taytay's fans enjoy listening to her songs, but there are also others who aren't happy about it including Harry Styles' new girlfriend Nadine Leopold.

According to Hollywood Life, it makes it difficult for the model to forget about Harry's relationship with the "Shake it Off" hitmaker if she keeps on writing songs about him.

"They feel like wherever they go, they are hearing Taylor's songs on the radio," their source claimed.

Their relationship is starting to get serious and there are even reports that the boyband member has asked her to move in to his mansion in Los Angeles. It will be easier for the two to focus on their relationship if his ex-girlfriend would stop obsessing on the British heartthrob.

"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," an insider revealed.
