Dylan Efron has a strong bond with his older brother, Zac Efron. David Efron and Starla Baskett welcomed son Zac in 1987 before welcoming son Dylan in 1992. Zac and Dylan's parents separated in 2016, and David went on to marry his second wife, Jenny. Jenny and David welcomed daughter Olivia, followed by son Henry. Growing up, Dylan and Zac didn't always get along due to their age difference - but as Dylan got older, things started to change.
