Having delayed a number of shows in Las Vegas in 2021, Celine Dion subsequently pulled the plug on her Courage World Tour last year to focus on her health.
However, reports have suggested that Dion is in the "final stages" of confirming details for a return to her Las Vegas residency, according to reports.
It has been suggested that Dion has been in negotiations with Resorts World over a possible residency in the past few months, which could take place later this year, or early 2025.
"It's basically a done deal. She's doing it", one source has said, with another adding: "she has a passion for getting back onstage, and she's gonna do it."
Dion's previous Vegas residency which ran from 2003 to 2007, was the highest grossing residency of all time. Such was the success of it, that was extended by another two years, which saw her playi 717 shows to more than three million people overall.
Rumours of a Vegas return comes amid reports that Celine Dion is set to perform at the opening Olympic Ceremony on Friday.
