Beatrice Miller, who is a finalist on the current season of X Factor USA, has hit out at her mentor after she was told to perform a song that she had no affinity with.

The 13-year-old was made to sing a rendition of Cyndi Lauper's 'Time After Time', but was met with criticism for the panel for the "boring" choice.

Music mogul Simon Cowell told her: "I thought the song was boring. It just went on and on, so it's song choice. For some reason, Britney isn't quite getting the right songs for you."

Spears then defended her decision and explained to Cowell: "Simon, she has more talent in her pinky than all of your contestants together."

Following the show, Miller spoke to E! Online and admitted that her preferred genre of music definitely doesn't fit with what she's been performing on the programme:

"My song was really boring, and I've been telling Britney that from day one. She just said, 'Get through it and try to connect with the song'. I don't think it really mattered to her that I didn't like it."

"I don't really like slow songs. I listen to Nirvana and Radiohead, not really the divas."
