Miley Cyrus might need an extra drink tonight in celebration of her 21st birthday.
The day before reaching this milestone, the singer's home was burglarized, as North Hollywood Police sources confirm to Us Weekly and other outlets that an investigation is ongoing, but multiple items were taken from the residence.
"She's extremely upset and a lot of personal items were stolen," a source says of Miley. "She's really shaken up about the whole thing."
The break-in took place Friday afternoon in Studio City, with the thief (or thieves, it remains unclear) making off with some rather expensive jewelry.
Fortunately, no one was home at the time of the crime and no injuries have been reported.
Miley, meanwhile, is hosting a marathon of programming on MTV today and will perform tomorrow night at the American Music Awards.
