​Brenda Song is dishing on some rare insights into petty moments with her husband Macaulay Culkin.

​The Secret Obsession star made a recent appearance on Cosmo Goes Deep along with her costar Kate Hudson, for the promotion of their show Running Point’s season 2.

​During the show the pair asked each other a series of questions. Kate questioned Brenda, “What’s the pettiest thing you and your partner fight over?”

​While Brenda took a moment to ponder, Kate shared her and her fiancé, Danny Fujikawa’s, petty fights, saying, “If I’m like working and I’m gone for two weeks and I end up watching an episode of a show that we were watching together, we can actually get into not a fight, but definitely an argument.”

​Brenda then shared that she and Macaulay sometimes get too competitive while playing games before bedtime.

​She detailed, “One thing that we can argue about is we do play Mario Kart sometimes like in bed. And then we get very, very competitive and we will like 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.”

​In a previous chat with Entertainment Tonight at the premiere of her show Running Point season 2, the 38-year-old American actress shared that her and Macaulay’s kids do not want her to doll up because they fear she would leave them.

​“The moment they see me dressed up, they cry because they know we’re leaving. Otherwise, I’m in pajamas most of the time,” the mom of two shared.

​For those unversed, Brenda, who has been in a relationship with Macaulay Culkin since 2017, welcomed two sons, Dakota (born 2021) and Carson (born 2022), with him.

​The couple, who met on the set of their 2019 film Changeland, announced their engagement in 2022.
