Los Angeles (dpa) – Singer Jason Derulo cancelled his US tour Friday after breaking his neck while rehearsing a stunt for the concert series, he announced to fans. “The pain of letting you down cuts me way deeper than this injury I've sustained,” the 22-year-old singer of the hit Watcha Say explained in a press release. “My fans mean everything to me, so I'm praying for a speedy recovery in order to perform for you in the near future.” The statement said that Derulo suffered an acute fracture to a vertebra that came close to leaving him paralyzed. A photo on his website showed him with a hospital gown and neck brace. “I fractured my neck doing tumbling & acrobatics 4 tour!,” Derulo said. “Always tryin 2 push boundaries 4 YOU! Like my new chain?” BM ShortURL: http://goo.gl/Hu1aJ Tags: Jason Derulo, Tour Section: Entertainment
