So this is all our fault. Got it. Chris Brown’s seizure was caused by stress and the “nonstop negativity” the singer faces, his publicist said on Saturday. Brown suffered a non-epileptic seizure on Friday, which his publicist Nicole Perna said was caused by “intense fatigue and extreme emotional stress, both due to the continued onslaught of unfounded legal matters and nonstop negativity.” Brown was examined by a doctor but was not hospitalized. Brown has been on felony probation since he plead guilty in 2009 to beating his girlfriend, Rihanna. Since then, he has been in and out of court, most recently having his probation revoked after a May 12 hit-and-run case.
