Jade Ewen has accused Rita Ora of sleeping her way to success.
The Sugababes star hit back at an apparent slight from the 'Radioactive' hitmaker, who claimed she walked out of an audition for the Eurovision Song Contest in 2009 because the oft-ridiculed singing competition would have ended her career.
Speaking about the annual music event in an interview, Rita said: ''Imagine if I'd stayed, it would probably have been all over for me. At best, I'd be a contestant on that diving show ... 'Splash!?' Yeah, 'Splash!' I love that show.''
The comment offended Jade, 25, who eventually represented Great Britain in the 2009 Eurovision Song Contest and was a contestant on the Tom Daley-fronted celebrity diving reality show earlier this year.
The singer fired back on Twitter: ''Easy to mock when you are enjoying success. Eurovision and Splash? Proud of both. Some manage to sleep their way to success some have morals (sic)''
Rita, 22, was accused by her ex-boyfriend Rob Kardashian last year of cheating on him with 20 other men while they were together.
He angrily posted on Twitter: ''She cheated on me with nearly 20 dudes while we were together, I wonder how many she will sleep with now that we apart?
''But I mean 20?!!! How can a woman who is so busy trying to start her own career have time to be with so many dudes all while in a relationship?! (sic)''
Rita never responded to Rob's claims but did claim they split because her hectic career meant she couldn't devote any time to him.
