Jason Derulo recalled instantly fearing the worst when he stumbled and felt a "huge heat" at the site of the injury.

The singer, 35, suffered an acute vertebrae fracture in January 2012 while rehearsing for his Future History World tour in Miami. He ultimately wound up having to cancel the tour, as his injury was so severe it could have paralyzed him.

Jason Derulo went through the "darkest time" in his life when he broke his neck in 2013 - but during his recovery, he wrote his "most successful" record.
