Video! Derek Hough and wife Hayley on DWTS after her medical emergency

You might remember, especially if you're a "Dancing with the Stars" fan, that Derek Hough suddenly left the judges' panel for some medical emergency.

Turns out it was his wife Hailey who had the issue. The two were on tour and suddenly his wife had a lifep-threatening brain bleed which required immediate attention and surgery. Derek was told she might not survive and it was touch and go. Fortunately the surgery saved her life and Derek was by her side the entire time. She had to learn how to walk again but did not know what kind of residual issues she would have. Now we know.

Tuesday night, Derek and his wife made an emotional appearance on the show to reveal that she not only recovered but was able to dance with her husband as if nothing ever happened...and it was remarkable.
