The "Genie in a Bottle" singer recently extended her Xperience residency at Sin City's Planet Hollywood, and she wants the former "American Idol" star to be a special guest.
She extended the invitation during an appearance on the "Breakaway" hitmaker's new TV talk show, which aired in America on Monday, September 16, telling Clarkson, "You have to come. Bring a fun group of people, because I love feeding off the energy. It's a great environment. It's a great place to be expressive and creative. You should come and we should sing a song in Vegas."
Clarkson confessed she would love to join Christina at the show, but added, "That makes me nervous."
