“Hannah Montana” may be a Disney franchise, but series star Miley Cyrus is such a hot property that networks owned by other media firms are pretty standing in line to get her to make an appearance. Fox announced that Cyrus will host “Teen Choice 2008” on Monday, August 4th. The 10th annual special will celebrate the hottest teen icons in film, television, music, comedy, sports and fashion. Cyrus could be an award winner as well, having been nominated in four categories. The CW’s “Gossip Girl” and its cast lead the pack of nominees with 14 in all.
