Ian Drew is a senior music editor at Us Weekly magazine. He says Hudson's way of grieving has been channeling her energy into work and celebrating what she has.

On Oct. 24 of last year, the bodies of her mother and brother were found in the family's Chicago home. Her 7-year-old nephew was found days later in a sport utility vehicle.
