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.
