The 'RIP' singer spoke up in support of Chris during an interview with week, saying despite his troubled past, she is standing by him.
Chris was convicted of assaulting then-girlfriend Rihanna ahead of the Grammys in 2009. He later spent time in jail after admitting to a probation violation.
But in a new interview, singer Rita has defended him.
She said in her Capital FM radio interview: "Chris Brown is strong, powerful and someone that is important to me personally and professionally and has a lot to do with why I do what I do.
"All the discrimination and all what people think? If you have a great song then no one cares. At the end of the day, if you have a voice and can sing like that and write like that. I've seen him in the studio and in his element and he's one of the best musicians I have seen.
"I love him on different levels, musically respected, such a good friend. I see how he treats his people and he's a good person with a great heart and a lovely family. It's really nice that we finally got together because, regardless of what's happened, the song is just amazing."
A tweet from Capital's own account said: "Awww, @RitaOra fangirling for her mate @ChrisBrown saying how much she has loved working with him! @ThisIsMax."
Some people, however, do appear to care and have taken to Twitter to express their surprise at Rita's comments. One wrote: "Nice one Rita, really championing women here. Disgrace."
