It appears Celine Dion herself is a fan of Richard Dunn's viral video, in which he dramatically lip-syncs to her classic "All By Myself" while stuck, all by himself, in the Las Vegas airport. "The video was hilarious and very touching," she says in a YouTube video made specifically for Dunn. "I loved it. But next time you're stuck all by yourself at Las Vegas airport for hours and hours, please be my guest at my show. And by the way, Richard, you're more than welcome to use my bathroom." Dion recently extended her Vegas residency through 2019, Rolling Stone notes. (More Celine Dion stories.)
