Celine Dion: My Heart and Show Will Go On ... Honoring Rene

Celine Dion will return to her Vegas stage Tuesday for the first time since her husband Rene Angelil died, and she plans to continue paying respect to him.

We're told Celine's completely changing her show at Caesars Colosseum -- it now begins with a 10 minute long tribute to Rene.

Celine has 12 shows before going on hiatus in mid-March, so the tribute will be part of the act at least through then.

As her manager, Rene played a huge role in catapulting Celine to stardom. She's already had an emotional send-off for him at Montreal's Notre-Dame Basilica and a Vegas ceremony to honor him. Tomorrow night's opener should be another tearjerker.
