Brenda Song says the worst fight she and Macaulay Culkin have is over Mario Kart — played in bed, seriously competitive and sometimes ending with a mild grudge.
Her account is striking because Song and Culkin have been seen together at a string of high-profile events in recent years, and because the couple have built a family life that Song describes in affectionate terms. They attended the ceremony honoring Culkin with a star on the Hollywood Walk of Fame on December 1, 2023, showed up together at Netflix's Canelo v Crawford Fight Night at Allegiant Stadium on September 13, 2025, and appeared at the 83rd Annual Golden Globe Awards on January 11, 2026.
Song used those public moments to underline the private rhythm of their life: playful arguments about video games, shared interests and two children. She said simply that she and Culkin "have two children together" and that he is, in her words, "like my unicorn." The line came amid a longer description of how the two navigate work and home: "He understands my work, we can talk about football, we talk about basketball, we can cook together. I think I just really lucked out."
The couple’s history gives those small domestic details a sharper edge. Song said she and Culkin first met in 2014 through their mutual friend Seth Green, at a time when Song and Green’s short-lived sitcom Dads had just been canceled. Song recalled that Culkin "was trying to be funny about our show being canceled and I was not having it," a stumble that undercuts any tidy romance-at-first-sight story: Song said it was not love at first sight.
Three years later, Song said, Green brought the two back together on the movie Changeland. After working on that film, Song said she and Culkin "started a fling" — the beginning of a relationship that by the mid-2020s included public appearances and a family life.
There is a small tension in that arc. Song’s memory of a jokey, awkward first encounter sits against her current description of Culkin as exactly what she wanted. The contrast — from an offhand joke about a canceled sitcom to calling someone a "unicorn" who understands your work and your hobbies — is the kind of human inconsistency that makes the couple’s routine arguments over Mario Kart feel plausible rather than performative.
Those petty quarrels, Song’s account suggests, are a kind of test rather than a fault line. They are about being competitive in a game and letting minor irritations stand for a few minutes — nothing like the early friction she described when they met. The games, she said, can get them "mildly mad" but the anger does not stick: the fights are small, domestic, and easily framed as a joke.
Put another way: the story Song tells about her relationship with Culkin is not one of constant drama but of ordinary give-and-take, with a competitive streak in the bedroom and a shared life in public. They met through a friend in 2014, were reunited three years later for Changeland, started a fling after that, now have two children, and keep finding reasons to show up together, from a Walk of Fame ceremony to sports events and awards nights.
So when readers ask whether the couple’s arguments are serious, Song’s own words answer it: no. Their spats are petty, rooted in games and momentary frustration, and buffered by a partnership she describes as understanding and rare enough to call a unicorn. If the biggest thing they fight about is Mario Kart in bed, their relationship — by Song’s telling — is more steady than sensational.
