Fabolous is still putting the finishing touches on his upcoming album, “There Is No Competition 2: The Grieving Music,” but he almost lost some of his rhymes at Morton’s Steakhouse in Hackensack, NJ, the other night. The rapper paid more attention to his BlackBerry than his meal, but forgot the phone when he left. When a quick-footed server ran out to the parking lot to return it, a grateful Fabolous admitted he’d been writing lyrics on it all evening.
