Isac Hallberg (born in 2007) is the son of Swedish actress Rebecca Ferguson and businessman Ludwig Hallberg.He grew up in Simrishamn, a coastal town in southern Sweden, largely out of the glare of fame—thanks in part to his mother’s insistence on protecting her children’s privacy.Isac has a younger half-sister, Saga, born in 2018, the child of Rebecca Ferguson’s marriage to Rory St. Clair Gainer.Although his mother is a well-known figure in film and television internationally, Isac leads a relatively quiet life. Publicly, he attends school, spends time with friends and family, and is rarely involved in media or social media activity.Because Isac is still young—around 17 years old as of early 2025—there are no reports of him having a career, public profession or personal net worth.His mother, Rebecca Ferguson, is estimated to have a net worth of several million dollars; however, that is hers—Isac’s financial status remains private and unreported.
