THE HILLS star Heidi Montag plans to dominate the music charts across the globe - insisting her career will rival that of superstar Madonna. The 21-year-old aspiring singer has been using the Like a Virgin hitmaker as an inspiration during work on her debut album. She says, "But it's not like with most pop artists, where they have a song sent to them that has nothing to do with their emotions or lives. It's all about me and my life. I'm taking my time to make sure it's a classic. "I don't want to be the next pop person who's in or out. I want to be like Michael Jackson, Madonna, Stevie Wonder - all the greats."
