Louis van Amstel was not included in the list of professional dancers on season four of Dancing With The Stars because of his height. All the female celebrity dancers were 5'9" or taller and he is only 5'8" tall.
In September of 2006, Louis van Amstel walked the catwalk, along with Lisa Rinna and Harry Hamlin, at Runway For Life Benefiting St. Jude at the Beverly Hilton in Beverly Hills, California.
Louis van Amstel: (on the check he received for $200,000 for his non-profit, Vision Worx) This money is so great because we can invite phenomenal dancers to be in a company and people around the world can enjoy their talents. Because of people like Enrique, we want to bring dance back, not only while Dancing with the Stars is on, but for the next 20 years, at least.
Louis van Amstel: Although the rumba is a slow dance, I've given Monique a lot of move requiring skills and not just be slow and tender -- which we've had enough of!
