Scott Storch, the former Roots keyboardist and producer at Center City's Sigma Sound Studios, owes more than $500,000 in taxes on his $10.5 million home in Miami, reports the Miami Herald's Joan Fleischman. Storch, 34, who produced tracks for Mariah Carey, Paris Hilton and Beyonce, and who reportedly used to earn $90,000 per track he recorded, didn't let any of his cash burn a hole in his pocket, lavishing gifts such as a Bentley on former girlfriend Lil' Kim and jewelry for Lindsay Lohan. Now he's in arrears on child support for one son, leading to a bench warrant for his arrest, and he has been sued over the paternity of a 16-year-old boy whom the 34-year-old Storch may have fathered in his teens. Storch's attorney, Guy Spiegelman, told the Miami Herald his client "intends to honor all of his obligations. "He was a victim of mismanagement of his business enterprises, resulting in his current predicament," Spiegelman said.
