Miley Cyrus refuses to perform on `The Voice`, thanks to Christina Aguilera

Los Angeles: Pop star Miley Cyrus has reportedly refused to perform on `The Voice` because of her dislike for Christina Aguilera, who judges the talent show. Although the 33-year-old Aguilera is currently on a two-season break from `The Voice`, Cyrus has refused to appear on the programme over its affiliation with the former, reports contactmusic.com. "Miley is no friend or supporter of Christina, despite the fact they have a lot in common, including long associations with Disney and using some of same people through the years on their respective business teams,” a source told RadarOnline.com. "Even if Christina has temporarily stepped aside, `The Voice` is still Christina`s show and Miley doesn`t want to lift a finger to help that woman,” the source added.
