Frankie Valli and son Francesco have had their ups and downs in recent years. Francesco is the eldest son of Valli and ex-wife Randy Clohessy. The Four Seasons frontman also shares twins Emilio and Brando with Clohessy. He and ex-wife Mary Mandel share daughter Antonia and late daughter Francine, who died in 1980. Valli was also the adopted father of Mandel's daughter Celia from a previous relationship, who also died in 1980. Valli and Francesco's issues first made headlines in April 2024 after Emilio filed a restraining order against his brother.
