Rita Ora gets ''suspicious'' of Calvin Harris when they're apart.

The 23-year-old singer has been dating the 30-year-old DJ for the past year and when they have to spend long period of time away from one another, she admits she feels insecure.

She explained: ''I don't get jealous, I get suspicious. Any girl would, though. It's only because you miss that person, that's really the reason.''

The blonde beauty has cut down on her partying since she's been in a relationship and enjoys going out for a romantic meal with Calvin.

She explained: ''Instead of going out to party with friends, I go to dinner with my boyfriend. I'm only 23 and he's 30 so there are a lot of things I'm

learning along the way that he's very patient with. It's just great to have someone there who cares about me.''

Although their relationship is going strong, the 'I Will Never Let You Down' singer still hasn't thought about marriage or having children.

Asked if she is ready for marriage and babies, she told Britain's HELLO! magazine: ''Oh, wow, I guess not. But I'm in a happy place right now. I'm just enjoying myself.''
