"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," a source said. "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," the source continued. "He's let the teens down."

Ora also wrote on her Twitter Saturday, "Guys I am so sorry. I will make it up too you. I promise. I'm devastated. I love my fans."

Despite being linked to Ricky Hilfiger lately, Ora recently told Glamour that her breakup from Harris was really difficult. "I'm doing better than I thought," she said about the summer breakup. "I adore him and he's such an amazing human being. It was more about the situation. It was inconvenient. It sucks. It wasn't about 'us.' It was about the world we live in."
