Miley Cyrus may be past her wild child days where she swung nude on a wrecking ball in music videos. But she still likes to get naked and party hard every now and then! The 28-year-old singer says that she stripped off her clothes and climbed the iconic sign above the Hollywood Roosevelt Hotel during Flaming Lips lead singer and close pal Wayne Coyne‘s 60th birthday bash on Jan. 13. Miley’s stunt would have gone unknown, if she hadn’t told the world about it in an Instagram story.
