Rita Ora is "grateful" for Chris Brown's "support"

Speaking to Billboard magazine, she said: "I respect Chris' work and I thought the tone of voice fit perfectly with the record. There's a lot more to think about than how many songs Chris has out at the moment. I'm just a fan, and I'm very, very grateful that he wanted to support me."

Rita is getting ready to release her second album - the follow-up to 2012's 'Ora' - and admits she does feel "pressure" for the LP to do well because has the need to succeed in all aspects of her career.

The 'X Factor' judge explained: "(Pressure) is always there. It's just in my subconscious at all times - that's the world we live in unfortunately. So I try not to focus on that and just do the best at what I can do."

As well as her music career and new 'X Factor' job, Rita has also branched out into acting with roles in 'Fifty Shades of Grey' and 'Southpaw' and into fashion with deals with Adidas and DKNY but she won't let anything distract her from her day job of being a pop star.

She said: "My favourite thing ever in what I do is performing live. It's about not having any rules. I've been very adamant on making sure that there is a sense of freedom on my stage, whether it's outfits or being comfortable in your sexuality, whatever. I'm very proud of what I am."
