The "Ellen DeGeneres Show" DJ, Stephen "tWitch" Boss, passed away at age 40.

He passed away, according to his wife Allison Holker Boss.

He was our family's rock, the best husband and father, and an example to his followers.

Many people uploaded videos of him dancing and their memories of him on social media on Wednesday as they paid tribute to him.

This celebration marked his 40th birthday. My heart breaks for his family, particularly Allison and their adorable children.

Graduating from Lee High School in Montgomery in 2000.

He attended Chapman University and Southern Union State Community College to pursue dance performance.

Boss placed second in the television talent competition "Star Search" in 2003 and was a semifinalist on MTV's "The Wade Robson Project."

His rise to fame began when he finished second on "So You Think You Can Dance" in 2008. 

He would later come back to judge the dance competition.
