Katy Perry dressed up as Freddie Mercury, lead singer of Queen for her birthday party at Siren studios in Hollywood last night. It seems that the look she went for was Freddie’s early glam-rock spandex days.

It wasn’t until later on that Freddie acquired that West Hollywood leather man look and super short hair. Katy’s invitation was a picture of her head on a platter and asking invited guests to dress up as a “dead celebrity” or a “celebrity whose career is dead.”

What an odd way to celebrate. Then again, she is odd! More embarrassment for her preacher parents.

Rapper and hip-hop producer Dr. Dre’s 20-year-old son has died. His spokesperson released the following statement:

“Dr. Dre is mourning the loss of his son Andre Young Jr. Please respect his family’s grief and privacy at this time.”

Young Jr was found in his bed this past Saturday morning by his mother. After she was unable to wake him, she called paramedics, who responded and after their efforts to revive him failed, he was pronounced dead at the scene.

According to the coroner’s spokesperson, Young had spent the previous evening with friends. His mom told police that he got home Saturday at around 5:30 a.m., and that she’d heard him in his bedroom. Police said they did not suspect foul play.
