Hey now, hey now, Hilary Duff's husband has some thoughts about her comeback single "Mature."
While theories surrounding the inspiration behind the diss track has ranged from the singer's ex Joel Madden to Leonardo DiCaprio, who's garnered a reputation for dating women until they turn a certain age, Matthew Koma believes his wife was singing about someone significantly older.
"I think it could be about Bernie Sanders," the musician quipped in a joint Apple Music 1 interview with Hilary on Dec. 4, saying that he feels "less threatened" by the 84-year-old than other possible muses fans have suggested. "I have a few of my own."
But, as Hilary joking pointed out, it would be "too obvious" to sing about Bernie and other men around his age, listing off examples including Dick Van Dyke, 99, Patrick Stewart, 85, Morgan Freeman, 88, and Danny DeVito, 81.
"I like these suggestions a lot more than Leonardo DiCaprio," said Matthew, 38, as Hilary noted that she does "love Danny DeVito."
He added to the Lizzie McGuire alum, "You love a short king."
Indeed, speculation around "Mature"—Hilary's first single in a decade—has run rampant online, with many believing that it's based on a May-December romance similar to the one Hilary, 38, and Joel, 46, had in the early aughts.
“She looks like she could be your daughter / Like me before I got smarter," Hilary sang on the track. "When I was flattered to hear you say / You're so mature for your age."
So, is "Mature" about the Good Charlotte frontman? Joel's wife Nicole Richie—who's close friends with Hilary—doesn't seem to think so.
"'Mature' is not the word I would use to describe us," she captioned a photo of herself and Hilary laughing on Instagram Story in November, “but regardless, this song is a BOP."
