Given Taylor Swift's relationship spotlight, it seems Calvin Harris may be approaching it in every way angle, if their dating rumors are to be believed.

According to Hollywood Life, it is possible fans will soon hear a song collaboration between Taylor Swift and Calvin Harris.

"Calvin is going after Taylor pretty hard, he's been sending her songs and brought her out to Vegas, he wants to work with her and she's said yes," said an alleged source.

"She never saw herself as an EDM kind of girl but she's  really changing as an artist, she doesn't want to get put in one little box so she's trying everything. She just wants to create great music, whatever form that takes. She likes [Calvin] but she's not just going to jump into anything with him. She's making guys work for it because she wants to make sure that it's the right thing for her. At this point he's still chasing her"

Some have branded Calvin Harris as a heartbreaker, so perhaps fans are worried about Swift's alleged dating rumors, after photos emerged showing the pair spending time and being affectionate with each other.

"There's no doubt that Calvin has had a long string of female admirers," said a source to Radar Online.

"He's also been a bit of a player in the past, but he wants to do right by Taylor. Calvin has enormous respect for Taylor, and he's been incredibly gentlemanly so far in their courtship. For that reason, her friends, knowing full well about his past reputation, are going to give him the benefit of the doubt and trust him with Taylor."
