Singer Rita Ora doesn't find her experiences with past boyfriends interesting enough for her to write songs about them.

The singer, who has had various relationships in the past, says that she isn't bothered about her failed relationships and so doesn't feature them in her tracks, reports femalefirst.co.uk.

"I don't think I care enough about them to write a song about them," Ora told The Sunday Times newspaper's Style magazine.

Ora split from Calvin Harris last year, and she was subsequently banned from performing any of the tracks he'd produced for her forthcoming second album.

During a recent performance of the song "I will never let you down", the singer changed the lyrics to "I might have let you down". She says it was her way to say that she isn't "ashamed" of the failed relationship.

"I interpreted it like that because I wanted people to see I wasn't ashamed. It's normal for a 23-year-old to have a failed relationship, but the difference is, there are a lot of people watching. You know, it's life."
