New dad Oscar Isaac has hinted he is secretly married after referring to his partner Elvira Lind as his "wife" in a new interview.

The Star Wars: The Last Jedi actor was taking part in a recent BuzzFeed video segment with co-star John Boyega when they were asked to read a series of funny Twitter posts about themselves from fans lusting after the pair.

Picking up one piece of paper, the 38-year-old read out loud: "Sexy ways to spice up the bedroom: wear an Oscar Isaac mask," prompting him to quip, "That's what I tell my wife to do all the time!"

His response suggests he and his longtime girlfriend have quietly tied the knot, a claim further fueled by the gold band Oscar wore on his left ring finger in the BuzzFeed clip, which was posted online on Thursday (14Dec17).

Fans have since noticed Danish filmmaker Elvira sporting a similar piece of jewelry as she joined her man on the red carpet at the London premiere of his new movie on Tuesday (12Dec17).

Representatives for the couple have yet to comment on the speculation.

Oscar and Elvira are known for keeping their personal lives private. They previously worked together in 2013 on the Staircase Sessions website, producing music videos, and their relationship subsequently turned romantic, although they only went public with the fact they were dating at the 2016 Golden Globe Awards in Los Angeles, where Oscar was shown on camera planting a kiss on his date after landing the Best Actor in a Mini-Series or TV Movie honor for Show Me a Hero.

They welcomed a son, their first child together in April (17), but never commented on Elvira's pregnancy or the baby's birth until July (17), when Oscar told The New York Times they had named the tot Eugene in honor of his late mother Eugenia, who died in February (17).
