Celine Dion ended her 16-year Las Vegas residency at Caesars Palace in the most Celine Dion way possible!
Celine noticed a fan getting up to go use the restroom -- so she paused the music and WAITED for him to come back from the bathroom! Of course, she couldn't just let him walk back to his seat in peace. Celin Dion then went onto to call the man up to the stage, and refuse to shake his hand LOL -- WATCH the video here!
