Music mogul Tommy Mottola is to be a dad again. His wife, Latin superstar Thalia, is expecting their second child later this year. The former Sony boss wed the actress, 39, in 2000, and their daughter, Sabrina Sakae, was born in 2007. Mottola, 61, who has two other kids, Michael and Sarah, from a previous marriage, is delighted, sources say. Mottola, who nurtured the careers of Celine Dion, Destiny’s Child, Mariah Carey and Shakira, among others, is said to be in talks with Simon Cowell for a judging spot on his upcoming Fox show “The X Factor.” Mottola’s rep declined to comment.
