Taylor Swift and Calvin Harris have been dating for a while. But fans may have paid more attention to their relationship these past few days after Calvin's ex-girlfriend, Rita Ora, opened up to Marie Claire about her untoward experiences while dating the DJ.

"There was a reason why I split up with him." Rita Ora reportedly said, as quoted by Celeb Dirty Laundry. "And there was a reason why I'm at this point in my life where I feel like I have so much musical freedom, and I don't have to explain myself to anybody. It was more of a thing where I was in awe."

"I was at that point in my relationship where I felt he could do no wrong. I thought he had my back and that he'd never steer me wrong. But then 'I Will Never Let You Down' came out, and everything started to go a bit weird. I don't know if it was because business was mixed with personal or what."

With Rita Ora dishing out on her beef with her ex-boyfriend, many are speculating: will Calvin Harris would also subject Taylor Swift to the same heartbreak? It might be far from it. It seems that the "Blank Space" singer has more power in their relationship than the DJ. According to a separate report by Celeb Dirty Laundry, Taylor Swift is reportedly ordering Calvin Harris to quit smoking.

"Taylor is very anti-smoking." a source reportedly told Life & Style. "She has explained to Calvin that it is not a deal-breaker, but she is worried about his health. She has confessed that sometimes his smoker's breath turns her off. That's why she insists that he brushes his teeth and uses mouthwash after he has been puffing. She doesn't want him to ruin their make-out sessions."

Mirror has also reported that Taylor Swift has been making Calvin Harris petsit her cat, Meredith. The DJ doesn't seem to mind doing the job for his girlfriend and even posted an Instagram video of the cat drinking from a running tap.
