Marie Osmond appeared on The Late Show with Stephen Colbert on Monday, September 16, and even beat the host in a race to see who could list all of their siblings' names in order. The two talked about Donny and Marie's award-winning Las Vegas show, which has been running 11 years. When the show wraps up this November, Marie will have performed more shows on the Strip than Elvis and Celine Dion combined. "We have been very blessed," Marie says of the show and the numerous awards it has received.
