0123-celine-dion-splash-01Celine Dion endured her second funeral in as many days ... this time burying her brother.

Celine, her mother and sister arrived at a chapel in Quebec to bury Daniel Dion, who died one week ago today from cancer.  

It was a stark contrast to Friday's funeral for Celine's husband, Rene Angelil ... only a handful of people, mostly family members, attended.  Celine's 3 kids were not present ... clearly too much to bear.
