Could Rita Ora be getting her revenge through music after her film success may have caused her breakup? A new report said that Ora is writing a "revenge song" about her ex-boyfriend, which has fans wondering if it could be about Calvin Harris.

Why Rita Ora Won't Be Performing At Tonight's Teen Choice Awards

Reports go back as far as January that Fifty Shades of Grey put a strain on Ora and Harris' relationship, and now The Mirror reported last week that Ora was writing a revenge song comparing an ex-boyfriend to the devil.

The song is reportedly called Poison and the lyrics include such statements as "Like a serpent/From the Garden of Eden/You are like poison/Running in my blood."

Why Rita Ora Isn't 'Great' Despite 'Fifty Shades' Success

Harris reportedly blocked Ora from playing her song I Will Never Let You Down at last night's Teen Choice Awards because of their bitter breakup. No word if Ora will be on the Fifty Shades of Grey soundtrack yet, however.

In January before their split, The Mirror reported that Fifty Shades of Grey may have played a part in the end of their relationship. "Calvin is more private when it comes to fame than Rita, which also played a part," a source said. The source also said that their busy schedules, including filming the movie led to problems. "He'd be happy to meet someone who has nothing to do with the industry."

Despite the breakup, Ora has said that shooting Fifty Shades of Grey was one of the best experiences of her life and she even made a great friend in Dakota Johnson.

"She's a great friend of mine," Ora told Access Hollywood. "She really eased me and she was really nice to take care of me." Fifty Shades of Grey opens in 2015.
