Very sad news. What an amazing horse. If you haven't seen her 2006 WEG Freestyle video, watch it. I understand she was in foal at the time she was euthanized.

Dressage mare Blue Hors Matine, whose dressage freestyle at the 2006 World Equestrian Games in Aachen became an Internet video sensation, was euthanized today after breaking a leg in a paddock accident, Horse and Hound reported.
The 13-year-old Dutch mare was ridden by Andreas Helgstrand. She was retired from competition following a tendon injury at the Las Vegas World Cup in 2007.
Blue Hors Stud Director Esben Moller told Horse and Hound Matine broke her right forelimb at the knee while out in her pasture.
The YouTube video of her 2006 WEG freestyle has received nearly 10 million views.
