Back in early August, Simon Cowell broke his back in an electric bike accident. He fell while testing his new $20,000 bike in the courtyard of his Malibu compound (oo, la la!) in front of his 6-year-old son Eric and 14-year-old stepson Adam. Simon had to get spinal surgery, which sounds scary and serious. But mere days later his America’s Got Talent co-star, Howie Mandel, said the injured 61-year-old was doing “spectacularly well, considering”, and was expected to return to his AGT gig before season’s end (didn’t happen). Then, this weekend, a source close to Simon denied reports he was in rough shape, and he was, in fact, walking 10,000 steps a day (wow, 9,900 more steps than my record!). That source joked that Simon’s girlfriend Lauren Silverman had to “run to keep up with him.” Uh huuuh.
