Will Fifty Shades of Grey movie promotion go the same way as a recent interview for Rita Ora? While doing press at the launch of the DKNY MYNY fragrance on Tuesday, Ora walked out of an interview when the topic of her ex Calvin Harris came up.

Rita Ora Shows Off Fab Figure After Calvin Harris Song Rumors

There have been many rumors about Ora and Harris, including one that Ora is writing a "revenge" song about him that could end up on the Fifty Shades soundtrack. She didn't talk specifically about the Fifty Shades soundtrack, but in an MTV clip, Ora did hint that she was involved in "some soundtracks to movies."

"It's just about honesty," she said about the music she's creating for it. "It's my moment of truth. It's my love of pop mixed with my love of soul." She said new music should come out in January, ahead of the Fifty Shades film release in February.

Although Harris and Ora broke up earlier this summer, the feud came to a head when Harris wouldn't give permission to Ora to perform their song I Would Never Let You Down at the Teen Choice Awards.

The interviewer mentioned the rumors about Harris not releasing some of her songs and Ora replied, "Thank you. Bye, bye." She then walked away from the interview.

Ora is scheduled to sing with Iggy Azalea their hit Black Widow at the MTV Video Music Awards on Sunday and promote Fifty Shades of Grey next year.
