DJ Calvin Harris plays the dutiful boyfriend as he watched Taylor Swift's Miami performance on Tuesday as part of the "Bad Blood" hitmaker's 1989 World Tour.

One of her fans snapped a photo of Calvin Harris watching his girlfriend perform on stage as he tries to go incognito.

"Though the Scottish DJ did not hit the stage, there were plenty of stars that did including Pitbull, Ricky Martin and NBA basketballer Dwyane Wade who presented her with a custom-made Miami Heat jersey with 'Swift 13' on the back," Daily Mail said.

Taylor Swift has been very busy with her 1989 World Tour, which is a commemoration of the one-year anniversary of the album which sold at nearly 9 million worldwide.

Her busy schedule prompted split rumors between the two because of their long-distance relationship, and also allegedly because of his cheating ways.

Earlier this month, the British tabloid, Grazia, also claimed that Calvin Harris and Taylor Swift have broken up.

"The relationship went from 0-60 in a matter of weeks, so it was perhaps inevitable that things might come crashing down," the alleged source claimed, as shared by Metro.

But Calvin Harris took to Twitter to quickly deny the rumors about their split. The EDM DJ also threatened to sue the tabloids spreading rumors that he had a "happy ending" inside a Thai massage parlor.

In fact, Hollywood Life is claiming that Calvin Harris is making time for girlfriend Taylor Swift even if she's busy with her 1989 World Tour.

"As much as Calvin is busy with his own career," the alleged source claimed. "He has major leeway because he usually performs on the weekends, which allows him to travel a lot. And he intends to do that in order to be with Taylor as much as possible."

The source continued, "Calvin is going to make a very big effort to be with her more during her tour. They both want to figure out an arrangement and they are very confident that it will happen and benefit them both and their relationship!"
