Listen to Miley Cyrus on iHeartRadio

Miley Cyrus is working hard and playing hard.  After performing at the American Music Awards on Sunday night, the star hosted an after party that doubled as her 21st birthday celebration. 

According to "TMZ," she rented out the theater at the Roosevelt Hotel in Los Angeles.  The site published supposed footage from the party, which shows the singer watching what looks like exotic dancers standing in a circle with someone dressed in a costume as the character from "The Lorax."   

Meantime, "TMZ" is revealing more information about the burglary that happened on Friday at Miley's home.  Law enforcement sources are telling the site that the star lost 100-thousand-dollars worth of property.  Jewelry and designer handbags were reportedly among the items stolen.  Miley was not home at the time.
