Songstress Rita Ora has revealed that when she dated Scottish superstar Calvin Harris, things were great for a while but they soon went downhill. 

Speaking to the new edition of Marie Claire magazine, the 'Poison' beauty explained that perhaps the tension came from mixing business with their personal lives, but something really took a toll on their romance and eventually caused it to end:

"There was a reason why I split up with him ... 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."

Ora went onto add that she is definitely afraid of being alone, but doesn't think that should be an embarrassing thing to confess:

"I'm afraid of being alone. I'm not afraid to admit that, you know. I'm not embarrassed to admit that. I just hope it's not a never-ending cycle. Sometimes love just makes you feel crazy. And that feeling that we have as girls, just to have that feeling, even for five seconds, it's like crack. I mean, don't compare it to that, but you know what I mean. It's like comfort eating."
