Birthday cakes have been getting Miley Cyrus into a lot of trouble lately. The 19-year-old pop star was recently photographed licking a penis-shaped cake at her boyfriend, actor Liam Hemsworth's birthday party. This news comes just a couple of months after Miley's response to her own Bob Marley birthday cake got the former Hannah Montana star in even more trouble. We'd advise her to stay away from birthday parties for the next few weeks, but the young actress's history of wild moments proves that dessert treats aren't her only problem.
