Talk about a terrible Birthday Eve! While Miley Cyrus was counting down to her 21st birthday, some people planned on her being gone and robbed the singer's home when no one was home. Now, Miley is now spending her birthday being a sad panda. A source said: This is especially awful timing too because the singer has to perform at the AMAs on Sunday! Mileybird has shown that she’s a strong girl, so we’re sure she’ll be able to get through this scary time .
