Why did Matt Dillon never get married?

• As of early 2025, no public relationship has been confirmed. The El País Spanish newspaper profile described him as “discreet” about his private life.

• They are not related by blood or marriage. Diaz has been married to Benji Madden since 2015 and they have a daughter, Raddix, born in 2019 — not with Dillon.
