Dion's last show, "A New Day," grossed more than $400 million over five years. Now Dion has a new way to showcase her talent.
"I feel wanted. They got us back, they wanted us to have and present the best show possible," the singer said.
Her new show at Caesars Palace features a 31-person orchestra, plus guitarists, drummers, a pianist and three back-up singers.
Dion's return to Vegas could be a gamble.
When she opened "A New Day" back in 2003, unemployment in Nevada was 5.2. Now, it's 14.2 percent --the highest in the nation.
However, Caesars says ticket sales for the new show are so far exceeding those of her original one.
"It feels like home, I've been here 5 years. It's warm, it's a beautiful place to perform, and on top of that I'm with my family that grew and I have two more boys. Honestly, it can't really get any better than that," said Dion.
"With maturity and with time I think it feels even better. Because it doesn't feel like I really have to get it that way. It's just to get the emotion and the flair, the idea, and try to make it your own," she added.
Dion has sold more than 200 million albums worldwide. Past history indicates she's a sellout in Vegas and she's hoping that lightning will now strike twice.
Vegas executives hope this show will cement Dion as a Las Vegas legend, joining the likes of the late Frank Sinatra and the King, Elvis Presley.
