Rita Ora says her relationship with Calvin Harris is as magical as a Disney movie.

The 23-year-old singer is completely smitten with her superstar DJ beau and likened their one-year romance to animated love story 'Aladdin' in which the titular Agrabah thief falls in love with

Princess Jasmine.

Asked by heat if she'd found her Disney fairytale, she enthused: ''Aww. Which Disney movie? Are we talking 'Sleeping Beauty'? Are we talking 'Cinderella'? I would say it's more of an 'Aladdin'.''

The pair met after getting into a war of words on Twitter and Rita still can't believe how their relationship has developed, with Calvin even penning a her current single, 'I Will Never Let You Down'.

She giggled: ''It's so funny how it went from us kind of having a Twitter feud, to now us working together on a record.''

Rita has landed her big Hollywood break with a role in the most-anticipated film of the moment, the adaptation of kinky bestseller 'Fifty Shades of Grey', in which she plays S&M-loving billionaire Christian Grey's little sister Mia.

The platinum blond bombshell insists things weren't hot and heavy on set because leading actor Jamie Dornan is such a down-to-earth family man.

She said: ''No, it was incredible, cause his wife was there and he just had a kid so it was a very family orientated kind of thing, obviously when it's on set the kid stays at home.''
