Sinatra, who died in 1998 at 82, would have turned 100 on Dec. 12.
In a news release, Dion said "I've been singing Frank Sinatra songs in my shows for many years, his voice has been such an inspiration for me and it will always be."
Previously announced performers include Garth Brooks, Tony Bennett, Carrie Underwood, Alicia Keys, John Legend, Adam Levine and Usher.
More performers will be announced at a later date.
Sinatra inspired generations of singers
"Frank Sinatra was a mentor, colleague and dear friend of mine and he was the master of intimate singing," Bennett said in a release.
"Nobody could juggle a drink, a conversation and a perfect vocal as casually as Frank," Levine observed. "That's why I love him."
The taped event at the Wynn Las Vegas Encore Theatre will air as a two-hour CBS special on Dec. 6.
The Recording Academy will announce nominees for the 2016 Grammy Awards on Dec. 7.
