Behind the viral video cycles sits a grounded domestic partnership. Isaac met Danish writer and director Elvira Lind in 2012. Their collaborative relationship blossomed quietly away from tabloid scrutiny, culminating in marriage in March 2017, just weeks before Lind gave birth to their first son, Eugene, named in honor of Isaac's late mother, Eugenia.
Their union is deeply creative. In 2020, Isaac starred in Lind's live-action short film The Letter Room, which earned an Academy Award nomination. The couple operates their own production company, Mad Gene Media, crafting independent projects that focus on character-driven narratives. Lind often documents their life with an artist's lens, portraying Isaac not as an untouchable sex symbol, but as an active father and creative peer. His dating history before Lind remains largely conventional, including a long-term engagement to childhood sweetheart Maria Miranda, putting to rest speculative rumors about undisclosed past partnerships.
