(AllHipHop News) The Rev. Al Sharpton is calling for a national day of prayer tomorrow (February 12) to honor singer Whitney Houston. Whitney Houston was found dead earlier this afternoon in her fourth floor Beverly Hills Hilton hotel room. The singer was in Los Angeles to attend pre-Grammy Award festivities, in addition to the actual 54th annual Grammy Awards ceremony. “I am stunned at the passing of Whitney Houston whom I have known since the late 1980’s,” Rev. Al Sharpton told AllHipHop.com. “I have known her mother, the great gospel singer Cissy, and her aunt Dionne Warwick, down through the years, and the world is saddened by this great loss.” Tomorrow, Rev. Al Sharpton will preach at Second Baptist Church in Los Angeles, for Whitney Houston’s family and her memory. “The morning of the Grammys, the world should pause and pray for the memory of a gifted songbird,” Rev. Al Sharpton said. Details are below: February 12, 2012 8:00 a.m. Service Second Baptist Church Griffith Avenue Los Angeles, California
