# 5 of 12:  Miley Cyrus and Brandi Cyrus

With Miley-mania reaching a fevered pitch, it turns out there's more Miley to go around. Brandi Cyrus, Miley's older step-sister, is a fellow musician and actress occasionally performing both onstage with Miley and on the Nickelodeon show, Zoey 101. Unlike her stepfather's fresh-scrubbed natural daughter, the funkier Brandi sports a total of seven facial and body piercings, along with a double-cherry tattoo stamped on her upper arm. Quelling any notion of sibling rivalry, Miley's new album, Breakout, the first not involving the Hannah Montana franchise, debuted at #1 on the US Billboard 200 chart, ensuring a feverish cross-over appeal as her star continues its meteoric rise. She's currently at work on a feature film based on her wildly popular Disney Channel musical sitcom.

Brandi Cyrus on compound families: "Billy Ray is my stepdad but I've grown up since I was little calling him dad so I'm not going to change that."
