The Calvin & Rita split gets messy.
Oh no. It is horrible when break-ups go sour.
Now Rita Ora has pulled out of performing at the Teen Choice Awards - because Calvin Harris has 'blocked' her.
It sounds like an MSN relationship gone wrong - but no, this is serious!
Because Calvin wrote and produced the song 'I Will Never Let You Down' he has final say on when and where she can perform the song.
Mr Harris has reportadly pulled the plug on her live set at the Teen Choice Awards!
The MailOnline has been told by a source: “She had spent a considerable amount of time and energy preparing for her now cancelled performance of the song and is devastated to let her fans down in this way.
“It is surprising that he has made such a poor choice.
“This cruel move by bitter Calvin has impacted not only the Teen Choice Award production but the teenage fans expecting to see her perform. He's let the teens down.”
