Canadian star Celine Dion has staged her final show at Caesar's Palace in Las Vegas after nearly five years, BBC reported.

The singer has performed her "A New Day" concert 717 times since March 2003, taking more than USD 400 M by attracting almost three million people.

But she told her audience at the final show that the stage spectacular was almost derailed by pregnancy and bad reviews.

"At one point, it was like feeling like the Titanic was about to sink again. But we believed and we went on with it," Dion explained.

A theatre was built especially for the performances of the Grammy award-winning singer.

After the show's encore, Dion invited her husband and son, Rene-Charles, now seven, to join her on stage.

Rene-Charles repeatedly reached down to grab rose petals that rained down on the final bow, giving them to his mother.

"Most of us have left our families behind to give ourselves every night. I can assure you it was worth it," the star said.

Now Dion is to launch a 96-date world tour in Johannesburg, South Africa, on Valentine's Day 2008.

Comedian and singer Bette Midler will take her place at Caesar's Palace, with a production called "The Showgirl Must Go On".
