The milestone show coincides with Caesars Palace's 50th anniversary.
A statement posted on Celine Dion's Instagram account, read, "On March 25th, 2003, Celine performed her first of many concerts at The Colosseum at Caesars Palace in Las Vegas. Tonight, we are proud to celebrate her #1000th performance over 13 years!”
Dion kicked off her first Las Vegas residency, "A New Day...," on March 25, 2003, and it ended on December 15, 2007.
She then took a three-year hiatus, during which she recorded new music and went on the Taking Chances World Tour.
