Rita Ora thinks Calvin Harris is ''amazing.''

The 'R.I.P' singer split from the Scottish DJ in June following just over a year of dating but she admits she still has feelings for him and isn't over their break up.

She told Britain's Glamour magazine: ''We both work really hard, we're both all over the place. I'm not doing too great but I'm doing better than I thought. I adore him and he's an amazing human being.''

However, the 23-year-old star also admitted she would never have spoken about their split on Twitter if Calvin, 30, hadn't used the social media site to confirm their romance was over a few months ago.

She explained: ''Honestly, if Calvin hadn't done it, I wouldn't have. It took me five days to write three sentences. It was massive.''

Calvin wrote on the site at the time: ''To address speculation -- myself and Rita ended our relationship some time ago. She is a beautiful, talented woman & I wish her all the best. (sic)''

Meanwhile, it was previously claimed the 'I Will Never Let You Down' hitmaker felt ''embarrassed'' when Calvin announced the news because she was ''shocked'' by how public he'd made it.

A source said: ''Rita was left embarrassed when he tweeted that it was all over.

''She didn't think he was going to make the announcement, so she was shocked.''
