The 22-year-old singer admitted she was ''so lucky'' in her relationship with the DJ and revealed they are incredibly similar.
She told The Sun newspaper: ''I feel so small and looked after. I am very happy.
''I'm in such a happy place. I'm so lucky that I've found somebody who is exactly like me.''
While Rita claimed it can be ''difficult'' having a relationship in the public eye, she insisted they were in a ''great position'' to decide on the nature of their romance.
The 'How We Do' singer told Capital FM: ''It's always a bit difficult. There isn't really a clear answer when you have somebody that you really like and people take pictures of you liking that person.
''It's a bit of a weird scenario but I always just ignore them. But it depends on where you choose to go as a couple, what you choose to do and how private you really want things to be.
''We are in a great position right now with the Internet to put out what we want to put out and go with the flow, it's OK.''
