Macaulay Culkin, Brenda Song fight over THIS reason

Brenda Song pulled back the curtain on life with Macaulay Culkin.

It turns out their fiercest battles aren’t over parenting or careers, but over Mario Kart.

In a candid April 22 episode of Cosmo Goes Deep, Song sat down with her Running Point costar Kate Hudson and admitted that she and Culkin get “very, very competitive” when racing each other in bed.

“We will get like mildly mad at each other, for like cutting me off or like winning, beating me last minute. That’s probably the pettiest thing,” she confessed.

The revelation added a playful twist to a relationship that began in 2017 at Seth Green’s home and blossomed into an engagement in 2022.

Song has often described Culkin as her “unicorn,” saying their unexpected connection made their bond stronger.

Culkin, in an interview with Cosmopolitan, has called his wife the person he believes in “down to my bone marrow.”

Beyond the video game rivalries, Song has painted a portrait of a partnership built on shared passions — from cooking to sports — and a deep sense of trust.

“He understands my work, we can talk about football, we talk about basketball, we can cook together. I think I just really lucked out,” she said in an interview with Access Hollywood.
