Although the 22-year-old singer insists her relationship with the DJ is still too new for them to be in love, she admitted her feelings for him are getting stronger every day.
Rita told British GQ magazine: ''It's early. I'm not in love. But I'm definitely falling.''
While Rita is forced to spend time away from her family, friends and Calvin due to her jet-setting lifestyle, she insists there is nothing she would change about her life right now.
She said: ''You always have to sacrifice something when you want to achieve something.
''Of course, I get lonely and I get sad, but I made a decision to do this... I'm in an amazing position to change my life, and change my family's life.''
Rita previously claimed she is ''so lucky'' in her relationship with the DJ and said they are incredibly similar.
She explained: ''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.
''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.''
