This was the case recently.'Taylor is later thought to have written a song about Camilla, called Better Than Revenge.

Taylor claimed Joe broke up with her in a 27-second phone call in the October of that year, telling Ellen De Generes: 'It's alright, I'm cool. Phone calls can only last as long as the person on the other end of the line is willing to talk.'And he added: 'Anytime you are in a relationship for any length of time there are going to be issues. But Camilla was not best pleased and tweeted: 'No need for revenge. Those who hurt you will eventually screw up themselves & if you're lucky, God will let you watch (sic).'
