The release of Rita Ora's new single has been shrouded in controversy, with many criticising the pop star for collaborating with singer Chris Brown. The pair have collaborated on the track Body On Me but some have questioned why she would work with a convicted domestic abuser.

The X Factor judge has been busy promoting the track, which is expected to feature on her long-delayed second studio album, but Ora has been accused of forgetting her feminist values. One Twitter user commented: "Why did you have to work with Chris Brown? He's an abuser and a lowlife. Disappointing," while another hit out: "So I guess @RitaOra is over that whole feminism thing by featuring @ChrisBrown on her new single."

One critic described Brown as a "traitor to women", while another stated that the singer is a "known domestic abuser". In September 2014, Ora, 24, described herself as a feminist "in the Beyonce mould", adding: "That's the perfect description. I am a woman, I'm outspoken and I support other females. I love what men do in the world but women have equal power."

Listen to Rita Ora and Chris Brown's Body On Me:

She has also been vocal about feminism in relation to the music industry in the past, telling The Mirror in January 2015: "In this industry, all the heads of labels are men, but every artist has to prove themselves, regardless of their sex. I have always been very vocal about the women sticking together."

Critics of Body On Me are also referring to the 2009 incident, in which Brown, 26, attacked his then-girlfriend Rihanna following a pre-Grammy awards party in Los Angeles. The Loyal singer later pleaded no contest to a felony assault and was sentenced to community service and a five-year probation order, which he has now completed.

Ora has not responded to the latest backlash but she heaped praise on the r'n'b singer in June 2015, describing him as "strong, powerful, and someone that is important to me personally and professionally".

She continued: "I see how he treats his people and he's a good person with a good heart and a lovely family," Ora told The Sun in June. "It's really nice that we finally got together because, regardless of what's happened, the song is just amazing."

In the midst of the controversy, reports have emerged that Rihanna, 27, is furious with Ora for collaborating with her ex-boyfriend, adding fuel to their rumoured ongoing feud. In particular, it is alleged that RiRi is unhappy with the music video, which is yet to be premiere publicly.
