How much shows have Celine Dion done in las Vegas?

As of my knowledge cutoff in September 2021, Celine Dion has performed a total of 1,141 shows in Las Vegas. Here's a breakdown of her Las Vegas residencies:

1. A New Day... (2003-2007): 717 shows at The Colosseum at Caesars Palace

2. Celine (2011-2019): 425 shows at The Colosseum at Caesars Palace

Please note that Celine Dion's Las Vegas residency shows may have continued beyond September 2021, so the total number of shows could be higher. For the most up-to-date information, I recommend checking the official website or social media of Celine Dion or Caesars Palace.
