Rita Ora was nervous about making her feelings for Calvin Harris public.
The pop star initially refused her producer boyfriend's idea to record a song together and was wary of putting her emotions down into words on her number one single, 'I Will Never Let You Down', in case it jinxed their romance.
In an interview with the Daily Mirror newspaper, she revealed: "I thought it was a bad idea. I said, 'I don't know what's gonna happen, babe.' All that political s**t, I didn't want to think about it. But when we started to write, it happened so naturally it felt right.
"There was a moment when we were like, you know, we're both known. It could become difficult. This message, I won't let you down, is a message of hope. It's the little reality that we do have left in this... [fame bubble]."
Rita, 23, has become one of the most recognisable faces in the world since hitting the big time in 2012 with her summer anthem 'Hot Right Now'.
The Kosovo-born star has lost most of her old friends because they struggled to adjust to her new-found status and she doesn't have time to deal with their complaints that she has changed.
She lamented: "I have had some [friends] that you don't even recognise any more. It can be scary when people start to act weird around you. They even ask if they can go to the toilet.
"People say 'Rita has changed' but we are supposed to change. You have a career to change for the better and to succeed.
"It's not your job to persuade friends that you are the same. They have to accept I am going to change because I am working my b****y arse off.
"But you shouldn't worry about it, you should worry about your album and your shows."
