Celine Dion Is Ready To Return To Stage After Husband's Death

Celine Dion is about to take center stage for the first time since husband Rene Angelil died, but not to sing.

We're told Celine's back in Vegas where she'll honor her late husband Wednesday with a celebration of life service. The venue is the Caesars Palace Colosseum ... the site of her Vegas residency.
Celine will speak at the event ... but we're told there's no plan for her to sing.
Rene was laid to rest in Montreal at an elaborate funeral in the Notre-Dame Basilica. A day later, Celine buried her brother ... so it's been a rough start to 2016.
As we previously reported ... she's canceled her Vegas shows until February 23.
